Battle of Conformity and Non-conformity Essay

In Tom Schulman’s Dead Poets Society a group of bright students are enrolled in a prestigious New England private school named Welton Academy. This school stresses conformity and tradition as one of its trademarks. In order to survive in this school one must never challenge the institution. Dead Poets Society is a powerful example of the constant battle between conformity and non-conformity. Mr. Keating, a teacher at Welton, fights on the side of non-conformity and free- thinking. On the first day of school, he shows them a picture of past classes. He tells them that they are all in the Earth now, and they have a message for his current students. The message was â€Å"carpe diem†, or â€Å"seize the day†. He is telling them that one-day they will be dead, so it is imperative that they â€Å"make their lives extraordinary† and to â€Å"carpe diem†, seize the day. Carpe diem is important because he tells them to follow their dreams, but in many cases their dreams went against the principles of the school. Through his unorthodox teaching style he taught them that conformity was not necessary. Many of the poems he taught them all preached carpe diem, such as the following: Gather ye rosebuds while ye may Old time is still a flying And this same flower that smiles today Tomorrow will be dying. â€Å"Gather ye rosebuds while ye may† means that make your dreams come true before you die. However, they could never live their dreams if they conformed to what their parents wanted, or what their principal wanted. Another example of how his teaching promoted free thinking and non-conformity was the way he ripped out the introduction by J. Evans Prichard. He didn’t want his students to conform to Prichard’s views on poetry he wanted them to form their own views. He called the introduction â€Å"excrement† and yelled â€Å"rip it, rip it out†. Everyday in his classroom there would be a lesson that preached against non-conformity along with poetry. After reading a poem, Mr. Keating stood up on the table and said, â€Å"Why do I stand here? To feel taller than you? I stand on my desk to remind myself that we must constantly force ourselves to look at things differently.† He then invites his students to stand up. This is obviously a lesson in free thinking and non-conformity. He is saying that there is more than one view to everything, and he is inviting them to be unconventional. Mr. Keating  helps almost all of his students become free thinkers and non-conformists. This is illustrated at the end, when they all stand on their desks. Mr. Nolan, the principal at Welton, is a man who believes that tradition and conformity should be upheld in all cases. From the first day of school, he teaches them never to diverge from tradition. In the opening assembly, every word spoken by the students is done in unison. They all recite the four pillars, which are tradition, honor, excellence, and discipline. Neil Perry is a victim of society’s need for conformity. He is a Welton student, who has been entrapped in his father’s web of restrictions.

12 Angry Men †Critical Thinkers Essay

In Twelve Angry Men, a young man is on trial for stabbing and killing his father. The movie focuses on twelve randomly selected citizens who are assigned the duty of determining the fate of this 19 year old man. The jury is supposed to examine certain facts and determine the truth based solely on the evidence presented to them in court. It is assumed that the jurors will judge fairly and without personal bias. Basically, the jurors need to use critical thinking during this trial to figure out what evidence is factual and what evidence is false. Throughout the film, some jurors were better at critical thinking than others, some had obstacles to overcome before they could use good critical thinking skills, and yet others became critical thinkers at different points during the movie. Critical thinking played a key role in Twelve Angry Men. In order to be able to think outside the box, one must possess the ability to think unbiaslly, not bring personal issues into play, not be scared to put the ideas and doubts on the table, and to be level headed. The juror who possessed these skills the best and applied them better than his eleven other companions was juror number 8, played by Henry Fonda. At the beginning of the movie, juror 8 was the only one to vote not guilty on the first vote. Fonda’s character plainly stated â€Å"It’s not easy for me to raise my hand and send a boy to die without talking about it first†. This shows that he wanted to examine all the evidence and â€Å"facts† before coming to his decision. As the movie went on, juror 8 kept posing questions like â€Å"could it be possible† and â€Å"could he be wrong† to remind others that about reasonable doubt. Then Fonda’s character helped find holes in two key pieces of evidence, one being the knife used in the murder. The switchblade knife was supposed to one of a kind, but juror 8 takes a knife out of his pocket and jams it into the table next to the knife that was used in the murder. The knives were identical and Fo nda’s character explains that he bought it in the same neighborhood. The second piece of evidence juror 8 found reasonable doubt in was the old man’s testimony. The old claims he heard the killer yell ‘I’ m gonna kill you’, a second later he heard the father’s body fall and he saw the boy running out of the house fifteen seconds after. Juror 8 decided to reenact the scene, paying attention to detail my dragging his foot like the old man, as well as, measuring the distance so that it was accurate. Fonda’s character proved the old man’s story was false because it took thirty-one seconds. Juror 8 payed attention to details, analyzed every detail, put aside his biases, and opened the eyes of the other jurors, this is why he was a great critical thinker. Although there were some good critical thinkers in Twelve Angry Men, there were a few jurors who just couldn’t see outside the box until it was almost too late. Juror 10 seemed to be the most close minded of all his peers, resulting in bad critical thinking. There were instances where this character stereotyped the defendant racially by saying â€Å"those people†,†them†, â€Å"they are born liars† and â€Å"they do not value human life†. Juror 10 also referred to calling the boy ignorant and a slob. This juror not only treated the defendant poorly, but his behavior towards his companions was ignorant. Juror 10 was sarcastic, insensitive, lacking morals, holding grudges, and a l oud mouth. For instance, juror 10 sarcastically says â€Å"you’re a smart fellow aren’t you?† to juror 8 in response to a piece of evidence that had been shredded. All of these characteristics are ones that cloud the mind and do not allow common sense or critical thinking to come into play. There were three individuals that held so much grudhe, anger and aggression that it prevented them from thinking critically. One of these peers was juror 3. He claimed that the defendant was certainly guilty and his reasons for thinking this was completely prejudice. He brought thoughts of anger, resentment and revenge into the jury because his own son left him. For this he thinks and blames all young folks. Another jury who was a bad critical thinker is number 2. He tends to follow the crowd and feels like its an open and closed case. He doesn’t want to see the facts as they are nor does he want to listen to what anyone says. The last juror who bad at thinking critically was 6. Though he gave juror 8 a chance, the reason was because he was too narrow headed to figure out the evidence wase. He couldn’t connect any of the dots nor did he speak up very much in the discussion. Twelve Angry Men had good examples of how the average person uses critical thinking, which is while the process of conversion is occurring? For some reason the light bulb dings on after we listen to others explain their th oughts. Jurors 9, 11 and 7 were like most of us. During the trial juror 9 kept voting guilty until Fonda’s character started talking about the old man’s character and the woman’s eyesight. He voted not guilty after he thought about the old man’s character being alone, never had recognition in life for anything, and he wanted some so the old man lied. Juror 9 had to overcome his own perception of himself being old and not really needed for much in order to be a critical thinker and realize his opinions count too. Like juror 9, juror 7 had to overcome his preoccupation of going to a Yankee’s game. Throughout the film, he kept voting guilty and then after he heard jurors 8 and 10 talk about how the woman wore glasses and she didn’t have them on when she saw the murder. When this happened, juror 7 realized that there was reasonable doubt in the case. This only happens after he voted not guilty just to get to the ball game and Fonda’s character asks him why, which then makes 7 pay attention and think. Juror 11 was an immigrant who was scared and easily swayed by his peers. He had the obstacle of trying to stand up for himself, understand his voice counts and that his mind works just like others. Juror 11 conquered this obstacle when juror 8 was talking about the wound, he realized that the someone taller would have had to been the killer. He also explained to the others that a switchblade is use in an upward motion. Once these characters got over their obstacles, their critical thinking skills helped open holes in the case. All in all, Twelve Angry Men was a great learning tool to what critical thinking is and how to apply. This film taught me that you have to approach decisions in a certain manner. I need to keep an open mind, be level-headed, express my opinions and not judge others. Thinking critically implies that brain power of yours and your peers is needed to get a better understanding of everyday life. Respecting others around you is key. In order to use critical thinking, one must know what it entails.

Tranexamic acid and it's uses in pre-hospital an emergency medicine Research Paper

Tranexamic acid and it's uses in pre-hospital an emergency medicine - Research Paper Example The acid should not be used because it works against clots and hence activates intravascular coagulation and platelet usage. If a person with DIC is administered with the acid they end up having end-organ damage due to microvascular pathologies. The unwanted effects of the drug include nausea, vomiting, diarrhea, hypotension and disturbances in vision. Tranexamic acid is used topically. The acid is excreted in the urine (Twycross et al, 2002). Tranexamic acid has lately been used in emergency medical scenarios. Even though hemostatic dressings and tourniquets have prevented conditions such as hemorrhagic shock, the usage of tranexamic acid can have the same effect. This drug has been used for a long time in cardiac surgeries and bleeding disorders such as hemophilia. Now it is being used in taking care of hemodynamic conditions. A study by the name of Clinical Randomization of an Antifibrinolytic in Significant Hemmorrhage 2 (CRASH-2) tested 20000 patients with tranexamic acid across various countries. The results of the study showed that in an emergency trauma center where patients had serious bleeding, tachycardia and hypotension were given tranexamic acid. The recipients of TXA had a mortality of 14.5 %. Hence patients receiving TXA were at benefit. Another study is the Military Application of Tranexamic Acid in Trauma Emergency Resuscitation (MATTERs) was carried out which involved TXA infusion in an out-patient hospi tal. Tranexamic acid was administered in patients in which hemorrhagic shock was suspected. The results of the MATTERs study showed that individuals who received TXA had a mortality of 17.4% (Goodloe, 2013). Annually more than 500000 women lose their lives to postpartum events such as childbirth. Obstetric hemorrhage cause increased rates of maternal mortality. Hence systemic fibrinolytic agents are used in surgeries to prevent fibrinolysis to avoid blood loss after surgeries. A study

Rhetorical analysis of How to Mark a Book Essay Example | Topics and Well Written Essays - 500 words

Rhetorical analysis of How to Mark a Book - Essay Example The first category includes people who are fascinated by the exterior or superficial outlook of the books; the second category includes people, who collect a lot of books, yet they are partially aware of what is in their collection; and the third category belongs to those who own books as they are supposed to be owned. Adler emphasizes on the importance of the essence and the knowledge that is preserved in the books, and his third type of book owners have this habit of reaching to crux of the information that is locked in words. The author has compared reading books with consuming beef steaks. According to him one must not read through the books, like gulping food hastily. Rather a reader must read and digest every point in the book, like he is chewing and digesting a tasty meal. Further, he gives example of President Hutchins, who was according to him a learned person with the passion of reading. While quoting Hutchins case, the author tries to elaborate the importance of writing on books, and on margins on the printed pages. Adler admits that writing, while reading a book may be a laborious act, and it definitely consumes more time than just simply reading, but he says that this is actually how one can give respect to the ideas that are documented in book. However, he does not want the readers to condition reading with labor, he appreciates the relaxed mode reading of fiction and other easy to digest literature.

EXPLAIN WHY THE CHIEFDOMS OF THE PRE-COLOMBIAN CARRIBEAN ARE MORE Essay

EXPLAIN WHY THE CHIEFDOMS OF THE PRE-COLOMBIAN CARRIBEAN ARE MORE CLOSELY RELATED TO THOSE IN NORTHERN SOUTH AMERICA THAN TEH CHIEFDOMS AND STATES IN MESOAMERICA - Essay Example The chiefdoms of the Pre-Colombian Caribbean were closely related to those of the Northern South America. They were different from the Mesoamerican state because of the societal classification that existed. Before the arrival of the European communities, Costa Rica was inhabited by diverse groups of people who had diverse cultures. It was principally divided into the intermediate are (isthmo-Colombian area) and the Mesoamerican area. The isthmo-Colombian area included the Caribbean and the South America. On the other hand, the Mesoamerican area extended from Chiapas and the Yucatan Peninsula to the Nicoya Peninsula (Diehls 17). The intermediate area was made up of different societies that were ruled by different chiefdoms. However, these communities would form alliances, vassalages and community ties despite lacking a sole authority. This enhanced the exchange of culture and rules of community organization these different societies. On the other hand, the Mesoamerican area was governed by a sole chiefdom (Adams 12). There was no specific interaction between the Intermediate and the Mesoamerican area. Pre-Colombian society also shared key characteristics with the northern South America society. Unlike Mesoamerica, the society was organized based on hereditary chiefdoms. The boundaries of the chiefdoms in pre-Colombia and Northern South America were demarcated by prominent geographical features or rivers. Most of the settlements were demarcated by forests. The eldest son was accorded the inheritance of chieftainship. This tradition was embraced by all of the non Mesoamerican chiefdoms (Adams 34). Another similarity of Pre-Colombian society with northern South American chiefdoms was in the housing structure. Grandchildren, children and parents lived under the same roof. This implied that clan houses harbored as many as 100 inhabitants (Bruhns 83).

Civil War Essay Example | Topics and Well Written Essays - 500 words - 4

Civil War - Essay Example law was put forward as a measure to placate the South which was upset over the increasing number of free states and anti-slavery sentiments penetrating the government. The law enforced fines on all law personnel who did not arrest a run slave. Prior to this act, the fugitive slave act of 1793 was in action which demanded the return of run-away slaves from the free states. In other words, it was asking the North which termed slavery illegal to abide by the slavery laws of the South. This was in direct contrast with the Northern sentiments. In many states like Massachusetts that had abolished slavery during the eighteenth century, the idea of returning slaves was met with great resistance. The law was not only dangerous for the run-away slaves but also for the free blacks, people who were born and raised in the Free states. The law could easily be misused and these people could then be shipped to the South having been unjustly termed as run-away slaves. The law was not acceptable to the North as it was asking them to become part of enforcing slavery throughout the country. The intention of this law was exacerbate the ensuing tension between the North and the South, however it further increased the divide. The law gave rise to many abolitionist leader like Frederick Douglas who raised their voice actively against the discrimination. The fugitive slave act was soon followed by the Kansas Nebraska act in the 1854 which further increased the divide. The ultimate blow was however dealt during the Kansas killings when proslavery as well as antislavery supporters flooded from the North as well as the South to cast their votes. The ultimate result of all the chaos and bloodshed was the civil war itself which decided once and for all the fate of slavery in the country. The Civil War can undoubtedly be called as one of the most influential events in American history whose effects helped shape the American nation. It is important to study the causes of an event which is of

The Kung, Wogeo, Huichol, and Sherpas differ significantly in their Essay

The Kung, Wogeo, Huichol, and Sherpas differ significantly in their social organization. Use the ethnographies Boiling Energy, S - Essay Example However, these cultural practices differ from vast people in other parts of the world as depicted by four ethnographies derived from diverse parts of the world. Analysis The fact that different individuals in the world have their own practices is depicted by Richard Katz in his ethnography â€Å"The Kung - Boiling energy†. In the book, the author outlines the cultural and spiritual way of life practiced by the Kung people in the Kalahari desert in South Africa. One major captivating aspect that the book reveals concerning culture and spirituality is Kung’s unique dance that seems to provide the focal point because anthropologists consider it as a primary ritual that encompasses and expresses cosmology, medicine and religion in a simultaneous manner. The healing dance as it is commonly known is practiced at specific periods of the time of the year and amazingly, everyone in the community participates because these people believe that each one of them has a â€Å"sicknes s† on one way or the other (Katz 332). In this regard, the Kung people believe that illnesses could be physical, emotional or even spiritual and the healing dance simultaneously heals all illnesses irrespective of the sickness nature. Therefore, the healing dance contains much more than just healing because it helps individuals release tension and energy that eventually transform people’s inner feelings. On a general perspective, the healing dance represents the spirituality of the Kung people because after the dance these individuals feel nourished, rejuvenated and reborn just like an individual from the west would feel after seeking spiritual intervention from a church (Katz 332). Therefore, the healing dance greatly affects the religious life of the people of Kung. Another ethnography depicting a different social organization is Barbara G. Myerhoff in her book â€Å"Peyote Hunt†. The ethnography is a story of a Native American ethnic group from western central Mexico, whose culture and spirituality is signified by its ancient practices. Though the book encompasses vast research findings from other sources, the author brings out the Huichol’s religion and culture through personal experience. Ideally, the Huichol people practices vast rituals that involve weeping, singing and contacting the ancestral spirits. Among its numerous practices, the Huichol’s practice a ritual of deer hunting because they believe that deer meat is a source of nourishment due to the magic power that the meat contains. Prior to the magical meat granted by the deer, the hunting experience provides a deep spiritual connection and fulfillment because it brings together people and all creatures (Myerhoff 16). In addition, the Huichol people also adore the maize because they believe that it fosters morality and emotions in their own way of understanding. Though the interrelationship between the Huichol’s and the maize is weird they claim that maize is their life and they greatly interconnect. Generally, the deer-maize-peyote complex is the way of life that determines Huichol’s cultural and religious life because it helps them refresh their inner personality emotionally, physically and spiritually by hunting the Peyote, eating its meat and exercising the maize ritual (Myerhoff 16). On a different perspective, Ian Hogbin chips in with his

Inventory management at WAL-MART Case Study Example | Topics and Well Written Essays - 1000 words

Inventory management at WAL-MART - Case Study Example It also succeeded due to its global strategies. It became the first private-sector company in the world to have employed over one million personnel. It provides large spacious, wide, neat, brightly-lit aisles and shelves stocked with area for people to look around and provide a variety of goods. The average size of a Wal-Mart store is 107,000 square feet (www.walmart.com). Each store employs about 225 people. The employees are called associates as they hold value for the company (Frat Files). The stores feature a variety of quality, value-priced general merchandise, including (www.walmart.com): Wal-Mart operates each store, from the products it stocks, to the front-end equipment that helps speed checkout, with the same philosophy: provide everyday low prices and superior customer service. Lower prices also eliminate the expense of frequent sales promotions and sales are more predictable. Wal-Mart has invested heavily in its unique cross-docking inventory system. Cross docking has enabled Wal-Mart to achieve economies of scale which reduce its costs of sales. With this system, goods are continuously delivered to stores within 48 hours and often without having to stock them. This allows Wal-Mart to replenish the shelves 4 times faster than its competition. Wal-Mart's ability to replenish theirs shelves four times faster than its competition is just another advantage they have over competition. Wal-Mart leverages its buying power through purchasing in bulks and distributing the goods on its own. Wal-Mart guarantees everyday low prices and considers them the one stop shop. INVENTORY MANAGEMENT at WAL-MART Just-in-time inventory (JIT) is the concept of only carrying as much inventory as needed to supply to customers or consumers. Many companies are using JIT to reduce inventory costs and increase gross profits (Damiano, 2005). It makes more sense for companies to use their dollars elsewhere, rather than tying them up in inventory that is just sitting in a warehouse. Wal-Mart's inventory philosophy focuses on getting the good out of the shelves and into the customers hand in the quickest and most cost efficient way as possible and Wal-Mart is a paragon of such efficiency. JIT (Just in Time) is an inventory management technique invented by the Japanese. The first users of this technique are said to be the Toyota people and to this day, this technique is being effectively used by them. The concept behind JIT is that it optimizes the production process byreducing waste and keeping negligible inventory (Epps, 1995). Inventory has a holding cost in terms of keeping the excess inventory in warehouses whose rent has to be paid thus increasing the cost of the inventory. As a retailer, Wal-Mart has been able to achieve respectable leadership by using this technique to reduce the holding costs and decreasing wastages. The most important factor in having a Just-In-Time inventory system is to have the best logistics system in place. This includes having clear transport routes,

Giving economic circumstances over the last five years of how Tesco, Sainsbury and Morrisons have coped - Essay Example Falling house prices which were caused by shortage of mortgages made the economy to worsen and investor fell short of repaying their loans. This act made lending institutions to halt their loaning as they feared that their customers were unable to repay. Another cause for recession in United Kingdom was cost push inflation which made civil servants to squeeze their incomes and lower their disposal earnings. Citizen more so civil servants were very careful on every penny they spent for the cost of living had skyrocketed making them to evade any impulse buying. Lack of confidence with financial sector reduced confidence in real economy thus perpetuating low trading and therefore less revenue. Consequently, the retail sector which hugely depends on the buying behaviour of the customers was financially affected. The economic turmoil affected the overall retail sector worldwide to a large extent, top retail giants including Tesco, and Sainsbury also faced decline in their share prices due to a major brunt of the financial crisis (Hotten, 2008). Many retail sectors like the financial and other retail sectors did job cutting in order to combat the financial turmoil. Though the groceries giants like Tesco, Sainsbury and Morrison aimed at in creasing the jobs but due to the closure of some of the grocery depots like Tesco who closed its Daventry’s depot of Fast way distribution has resulted some job loss (The Telegraph, 2008). However, in the last five years except 2008 and 2009 UK witnessed a positive GDP growth rate (BBC News, 2011). At the end of 2009 UK recovered from the global recession which was caused due to the ripple effects of the failure of subprime loans and bankruptcy of the big financial institutions but can be hugely affected due to the predicted recession of 2012 which may happen mainly due to the debt crisis of the European countries (The Economic Times, 2011).

Fire investigation Essay Example for Free

Fire investigation Essay The triangle shirtwaist factory fire may have been cause by various flammable materials. The flammable materials that I could identify from the text that I was given were the lines of hanging patterns, the discarded rags on the floor and cutting tables, the shirts that have already been made, the table because they were probably made from wood and maybe the ceiling, walls and floor because that may have a material or something else flammable. The possible sources of ignition for the triangle shirtwaist factory fire could have been some faulty cables from the sewing machines causing the wires to rub together causing friction meaning that the cables would get hot and therefore this could be one ignition source. Another source could be gas lighters because in those days people were allowed to smoke in the work place. A gas lighter is not like a lighter nowadays because when it was alight it would not go out unless you put the cap over it unlike the lighter nowadays if you let go/ drop it the button comes back up instantly. Therefore, the gas lighter could have been a source of ignition if it was dropped. Another source of ignition could have been a cigarette. If it was not put out properly and was dropped, it could start the fire. Lastly, candles may have caused the fire because back in those days there would have been candles on each workbench so that the workers could see what they were doing because there were no lights back then. Due to there being candles around if one was knocked/ dropped it could have fell onto the rags on the floor causing the fire to start. Investigation of Liquid Combustion Introduction In this experiment, we will find out why some liquids burn at certain temperatures. Risk assessment Due to the fact that we are dealing with fire, long hair must be tried back goggles warn and lab coats on. There was also a risk of that somebody could bur themselves or set alight an object. In addition, if we were to pick up a hot crucible without gloves we must use appropriate equipment so that we do not burn our hands. Materials Crucible Heat proof mat Bunson Burner Tongs Splint String 1cm3 of kerosene 1cm3 of petroleum spirit. Method Petroleum (1cm3) was placed into a crucible and was then ignited using a lighted split. Once we lighted the petroleum and it had a burned we then poured 1cm3 of kerosene and attempted to ignite it using a lighted splint. After you have tried to light the kerosene with just a lighted splint place about 2-3 cm length of string into the crucible so that it is partly dipping into the liquid. Note the appearance how the kerosene lit. Results Petrol- The flame was quite tall and was yellow. The petrol ignited very quickly and there was soot around the edges of the crucible. When the petrol have burned the flame go smaller until it went out by itself. Kerosene- The Kerosene did not light so therefore there was no flame. Kerosene with string- The string slowly burnt away until it reached the crucible with the kerosene in which then ignited. It burnt with a tall, large yellow flame and left a lot of soot in the crucible when it had all burnt. Evaluation The experiments purpose was to investigate why certain liquids burn at different temperatures. By burning the petrol it showed us that it had, a low flash point so would ignite and burn easily. The kerosene by it selves did not burn meaning it have a high flash point, meaning it needs high temperatures to ignite and burn. Both the petrol and kerosene produced soot showing full combustion. Conclusion In conclusion, the petrol was the easiest ignite and could start a fire very easily while the kerosene did not light with just a lighted splint. It has a high flash temperature that why it is used as aeroplane fuel. Investigation of flames Introduction In this experiment we will be investigating how long it takes for a piece of paper to burn when lit from the top corner and the bottom corner. Risk Assessment Due to the fact that we are dealing with fire, long hair must be tried back goggles warn and lab coats on. There was also a risk of that somebody could burn themselves or set alight an object. Materials 2 sheets of A4 paper Heat proof mat Stands and Clamps Bunson Burner Splint Timer 2 sheets of A4 paper Method First we attached the clamps to the stands, and then attached a piece of A4 paper. We then lit the top of the short edge in the middle. It was then timed how long the piece of paper took to burn away completely and the time recorded. The experiment was then repeated with another piece of paper but lit at the bottom edge. Again it was timed until the paper was completely burned away and the time recorded. The Results `1st Paper: It started to burn instantly and spread downwards. The paper then dropped out of the clamps and fell to the table but it was not all burnt. After a while it all burnt out at 2 minutes and 11 seconds. 2nd Paper:. : It started to burn instantly and spread downwards. The paper then dropped out of the clamps and fell to the table but it was not all burnt. After a while it all burnt out at 23. 43 seconds.

Mislead the officer Essay Example for Free

Mislead the officer Essay He says this in a calm voice so not to annoy the officers. The officers dont await an invitation in to the house and with their authority they just step inside and Eddie says; Whats all this? He says this with an astonished look upon his face, making the arrival of the officers appear to be a complete surprise to him. But unlike the characters in the play, the audience has full knowledge of his deceitful phone call to the Bureau, so it is ironic when he appears to know nothing. The first officer in a demanding voice says; Where are they? He says this expecting a straight answer and no messing about. Eddie will now put on a puzzled expression and frown as he says; Wheres who? He makes out to be confused and pretends to know nothing about their presence as an attempt to mislead the officer. The officer doesnt accept his over up and tries to reason with him. This shows the audience that the officer is in control of the situation and is used to people making attempts to cover up and trick him. The officer now says; Come on, come on, where are they? This is said in a calm reasoning voice to try and just get an easy answer so they can capture the immigrants hassle-free. Again Eddie with a confused look says; Who? We got nobody here. He says this with a clueless expression and an astonished voice to try and convince the officer that there has been a mistake. In this first section Eddies attitude was ironic as he made out to be bewildered and surprised by their visit, but he was the one that contacted them about the immigrants in the first place. In the second section, we get to see Beatrices reaction to his deviousness, as she immediately knows that it was Eddies doing when the officers turn up. Eddie glances at Beatrice and she quickly turns her head away to make out she is tempered towards Eddie and he confronts her straight away; Whats the matter with you? He says this with a raised tone of voice to sound annoyed as shes accused him for the officers. Even though she only gave him one glance and angrily turned her head away, I want the audience to sense her suspicion and accusation, of him calling the Bureau. The officers continue to search the building and one approaches Eddie and asks if he has the correct room number, Eddie replies with; Thats right. I want him to say this in a shaky voice so the audience can sense that he is beginning to crumble and he is fearful of the consequences of his actions. He then stares at Beatrice and I want the expression on his face to say everything. He will put on an expression, which will suggest that hes just been hit by reality, and realises the terrible situation he has got everyone in to. Eddies fearful look at Beatrice will give her conformation of his deceitfulness. But there is still the question of why he is worried? Is it to maintain his reputation in the street or the fact that he has landed Marco and Rodolpho in trouble? Maybe Both? The fact that he carries on to deny that it was him that made the phone call suggests that its to maintain his reputation. When Beatrice accuses him I want him to get frustrated to cover up for his actions. After Eddies fearful glance at Beatrice, she too is struck with fear and this is made clear by the stage directions: [weakened with fear]: She goes on to say; Oh Jesus, Eddie. She says this in total disbelief and she puts her hands on her face. This will tell the audience that she cannot bear to know what her own husband has done. Eddie continues to protest his innocence and Beatrices final action is to turn towards him, instead of running. This shows the audience that even in crisis she will not desert her husband. Her final words to him are; My God, what did you do? I want her to say this with lots of fear and anger at Eddies actions. However the fact that she didnt run from him doesnt take anything away from the shock and horror she is experiencing at the realization of what he has done. In the third section, Catherine and Beatrice make a last effort to save Marco and Rodolpho and fight with the officers. However, the officers are immune to the pleas of Catherine and Beatrice for mercy and do not express an opinion or concern. I want Catherine to seem desperate and more aggressive when attempting to persuade the officers and I want her to be more frustrated and argumentative. The first stage direction says: Catherine [backing down the stairs fighting with the first officer]. The audience can immediately tell that she is taking a more aggressive approach. She then shouts; What do yiz want from them? I want her words to have aggression in so they know that she isnt going to back down. She then says; They aint no submarines, he was born in Philadelphia. I want the audience to see her determination to save Rodolpho and her sheer frustration at what is happening. On the other hand, I want Beatrice to be seen by the audience to be taking a calmer and more diplomatic approach. She tries to reason with the officer; Ah, Mister, what do you want from them, who do they hurt? I want Beatrice to say this in a calm, less-threatening voice, so not aggravate them. The officer takes little notice of Catherine or Beatrice and merely just says to Catherine; Step aside, lady. I want him to say this in a calm, but firm voice to show the audience that he doesnt want any trouble and remains in control of the situation. I want Catherine to now appear upset and infuriated. I will do this by using her body language and tone of voice. I want her to speak in a quite angry and distressed voice; You cant just come in the house and- I want her body to be blocking the officers from getting past. I also want her to really speak face to face with the officers, to look like she is trying to intimidate them. She becomes increasingly upset as her campaign doesnt seem to be working and she screams; No, you cant! Now, get outa here! I want this shout of hers to turn in to an upset scream as she realises that she cant save Rodolpho. The men proceed to take away the immigrants and Beatrice confronts them one more time. Instead of an aggressive approach like Catherine, I want the audience to see how Beatrice stays calm in the chaotic situation. Beatrice makes an emotional appeal about what drove the immigrants to leave their own country; what do you want from them? Theyre starvin over there, what do you want? I want her to say this in a persuasive voice to try and play on their consciences, but the officers just walk off. I want them to just ignore her to suggest to the audience that they are not affected by her emotional appeal and are immune to her pleading. From this section, the audience gets to see the aggressive and frustrated Catherine character that I wanted them to see and the calm Beatrice. The audience also gets to see the very calm and dominant officers who always stay in control of the dramatic situation and do not show concern or opinion to the pleas and appeals of Catherine and Beatrice. In this next section Marco performs the malicious act of spitting in Eddies face, which results in Eddie becoming extremely furious and mad at him. This is where I get to reveal the ruthless and unpleasant side of Eddie, which I want the audience to see. It starts when Marco breaks from the group while being escorted out by the officers and spits in Eddies face. This is a powerful dramatic moment in the play and is conveyed by actions, rather than words. I want the act of spitting in his face to not only show Marcos contempt for Eddie, but also contempt for Eddies breaking of the social code. By informing the immigration bureau a social taboo has been broken and the act of spitting in his face tells the audience Marcos identification of the culprit.

New product development

New product development Need in the Market The need for an eBook in the market was evident. In the information age, where volumes of data and information need to be exchanged, created, examined and organized, there was a huge void to be filled by a handy device capable of being carried around, having an interface big enough like a book, but not the limited capacity of a paper book. The books were omnipresent, even though depleting in number with the internet coming up. But for extended reading, the computer screen was too inconvenient. It took too much time to load up. It was unwieldy to carry around. Not everything was available in a format youd want it in. To look into what exactly the need was, lets us look deeper into some specific points. To fill the current void, the market needed a product that: Was not heavy on the environment, like books. There was too much paper and ink being used for relatively miniscule amounts of information. Replicated the book in terms of readability. The computer screen was strenuous to look into for too long. Further, the computer screen could not be seen in sunlight. It also was very hard to read at angles. Facilitated exchange of information without necessarily the constriction of holding a device and keeping the users eye fixed on it. For example, in the ultra mobile culture that is emerging, many users are either driving a vehicle for a big fraction of the day. They may be users who are working around the house too. Books, because of the undivided attention they required, were slowly being drifted away from. Did not require storage space. Books took up a lot of space. Theres only so much information that can be kept in the library in the form of books. Was not heavy. Books are heavy if you realize that just to move from your living room to the park outside with a few big books is not inviting. If youre travelling, its almost impossible. Was updated in real time. Books cant be, and computers are, as we saw, unwieldy. We now see how the Kindle fulfilled these needs. The Amazon Kindle and how it filled the gap The answer was an eBook reader. One such product is the Amazon Kindle. A quick glance at its features, benefits and how it fits with the market demand identified above is presented. Amazon Kindle: a software/hardware platform by Amazon.com for displaying e-books and sometimes, other digital media. The 3 versions are: Kindle, Kindle 2, and Kindle DX. The Kindle First Generation, which was Amazons first device, was released in the US in 2007 (on November 19). The Kindle uses an E Ink brand electronic paper display. It downloads content using Amazons Whispernet (propriety online store) using mobile networks. The Kindle 2 devices use the American ATTs service and some roaming partners that give wireless access internationally. Kindle does not have to be connected to a computer, and Amazon Whispernet does not require a subscription. All Kindles come with free access to the Internet over mobile networks in the US. Here is a look at the features and benefits you can find with Amazon Kindle. The screen looks like real printed paper. Kindle also became desirable because of its 3G connection service in more than 100 countries. Users are able to get the first chapters of books before purchasing them. The actual download takes 60 seconds. The Kindle DX features a larger screen and more memory to hold more e-books. The screen size is 9.7 inches which is pretty large for comfortable reading. Even the available memory of 3.3 GB is enough to keep to the tune of 3500 books. The screen boasts not having any glare or illumination. This doubles up as a major power saver. In addition, the words of the book, once displayed on the kindle, remain that way without consuming any power. So, in the domain of utilization of power, it is very efficient. About 500,000 book titles are available at its Kindle Store for international customers. Competitive analysis Porters analysis for the eBook industry Entry Entry barriers to the e-book industry are few, if any. The manufacturing process is relatively simple; except for the screen, the technology is well developed. The Kindle uses an electronic paper display manufactured by E-Ink Corporation and this same display can be found in the Sony Reader, the iLiad, the Cybook Gen3, and the Readius. However, there is a challenge of signing agreements with publishers so that the material can be released as an e-book. Perhaps the biggest obstacle that all the companies are facing right now is the lack of growth in the industry. Jinke has been in the business since 2000 but has sold only 150,000 readers, the most of all the companies. Rivalry The e-book market is still in an early stage and because of this, market price levels are still uncertain. There are significant variations in price between different producers of e-book readers. Amazon entered the market at a significantly higher price than Sony and many other competitors, but there are also other readers selling at $700 or more. Because the consumer base is so small, all producers would rather see it expand than steal customers from other manufacturers. Consequently, there is more incentive for manufacturers to improve their product and increase interest in e-books than to compete on price. Supplier Bargaining Power Supplier bargaining power is derived from the number of suppliers, availability of substitutes, and costs associated with switching to alternative inputs. There are two main inputs to the Kindle: screen and network technology. The technology used to create the specialized display on the Kindle is manufactured by the E-Ink Corporation. E-Ink is the leading firm in the electronic paper market and is a supplier to a variety of companies, including Sony and other e-book manufacturers. Since the electronic paper market is relatively new and does not consist of many firms, substitutes are limited. Given the state of the electronic paper market and the fact that electronic paper is a recently developed technology, E-Ink needs customers and hence E-Ink does not have much supplier bargaining power over Kindle. This could change in the future, depending on the popularity of the Kindle and the development of the electronic paper market. Amazon uses EVDO network technology, supplied by the Sprin t network. Kindle users do not need to pay to connect to the network, as Amazon covers the cost. Large EVDO network providers also include Verizon and Alltel, with other competing networks using a standard other than EVDO. This means that Amazons choice of networks for Whispernet is fairly limited. While not an issue now, if Kindle becomes much more widespread in the future, the company could face a holdup problem with Sprint if Sprint wants more of Amazons profits. Thus Kindles display and network suppliers currently do not have much bargaining power, but it is highly likely that if Kindle succeeds, supplier bargaining power will increase and may become a problem for Amazon. Publisher bargaining power is also important to consider since the Kindle is fairly useless without e-books. To increase the size of Amazons e-book library, it needs to obtain publisher permission for each book it converts. Publishers have a great deal of bargaining power in this respect; while there are many publishers, for each title one publisher has a monopoly. Thus, if Amazon wants a specific book for its Kindle, it will have to pay monopoly prices to the publisher. This effect can already be seen in the market for printed books, where much of the profit on a book is retained by the publisher. For a large publishing company like Random House, its profits are on the order of 10% of its revenue. On the other hand, a book retailer like Barnes and Noble has drastically lower profitability, with profits less than 1% of revenue. Thus publishers have a great deal of supplier bargaining power since they essentially decide which books become e-books and whether those books will be availa ble for the Kindle. Publishers can also require that Amazon sell only versions of their books that include Digital Rights Management (DRM), an attempt to prevent illegal copying of the content. Consequently, all books sold through Amazon on the Kindle are available only in the proprietary AZW format. Most competing readers also specialize in their own DRM format. Buyer Bargaining Power Kindle buyers have little bargaining power. Bargaining power is derived mainly from the ease of switching to a competing product and the value of the product to the buyer. Because both the Kindle and competing readers use DRM schemes, books purchased for the Kindle cannot be transferred to other manufacturers devices and vice versa. This is not the primary reason for DRM, but it is advantageous from Amazons point of view because it increases switching costs and helps to create buyer lock-in. The market for e-book readers is still young and small, so the majority of e-book reader buyers do not have a significant existing electronic library. Existing libraries are not yet an important factor in shaping consumers purchasing decisions. However, once the market matures a significant portion of sales will be to existing owners of e-book readers. Thus buyer bargaining power will decrease over time and be very weak in the mature market. Substitutes The main substitutes for Amazon Kindle are libraries, both brick and mortar and online bookstores, and Google Books. However, unlike the online bookstores and Google books, Kindle does not require a computer. Kindles free wireless connectivity which uses the same network as advanced cell phones enables buyers to shop from the Kindle Store directly from the Kindle device. Instead of having to travel to the local library or waiting for books to arrive from online bookstores, this wireless network can download a book in 60 seconds providing customers a more efficient and direct access to books. Although Kindle does not yet have access to as many books as some of these substitutes, it is progressively adding more books. Also, the Kindle stores everything a purchaser buys online; in this way, if a customer loses the Kindle, the reading material will not be lost, as would be the case if you had a paperback. The readers also do not have to deal with heavy or numerous books because of Kindle s light portability. The Kindle display looks like ink on paper, which is easier on the eye than LCD screens and comparable to printed media. It can also increase text size which is a clear advantage over books. Physical bookstores allow customers to browse books before purchasing. Amazon attempts to emulate this feature by allowing users to download and read the first chapter of any book for free. E-book versions of new releases and New York Times Best Sellers are $9.99, saving on average 60%, and many other books can be found for less. As for Google Books, Googles aim is to help people find and discover books and learn where to buy and borrow them. Although there are books that can be read online from start to finish, this is only the case for books in the public domain and out of copyright. For these reasons, Kindle compares favourably to these substitutes. Complements The size of the e-book library, other file types such as .pdf, .doc, and .jpeg, and the service to convert files to Kindle format are all complements of Amazon Kindle. The most important compliment required is the number of books offered to Kindle users. The day Amazon Kindle was released last year, the Kindle Store had more than 88,000 digital titles available for download and now has over 115,000 Books, newspapers, magazines, and blogs. Amazon also offers an email-based service that converts .html, .doc, .jpeg, .gif, .png, and .bmp documents to their Kindle format, AZW, or can load unprotected Mobipocket or plain text content. This AZW format is only for the Kindle which is a good strategy on Amazons part to tie the complement to the product. Kindle also supports formats for audio in the form of MP3s and Audible 2, 3, and 4 audiobooks, which must be transferred to the Kindle over USB or an SD card. With a variety of book options and supported formats to accommodate more customers a nd their various needs, the Kindle is a simple and convenient alternative to reading a paper copy book. Major Competitors This competitor analysis only compared the products on the basis of the technology but to sell the product, there is much more than mere technology which has to be projected. That is where marketing steps in and that is the area where Amazon has been at the forefront with its clear marketing strategy and its proactive and subtle innovations which keep them at the forefront of the E-book reader industry. Marketing strategy The marketing strategy of Amazon Kindle can be seen through the STP (Segmentation, Targeting and Positioning) analysis of the Kindle which would give way to the marketing mix followed by the brand. A typical buyer of a Kindle can be perceived as a businessman/businesswoman who does not have enough time and space to carry along the pile of books and newspapers when they go out on a trip or a business meeting. They want multipurpose equipment with no frills attached so that they can browse their favourite book whenever, wherever they can. The popularity of the Kindle can be seen in countries such as America and Europe where these kinds of users are easy in good number. The Kindle is sold on the website of Amazon that saves Amazon a lot of cost due to a direct supply chain. The communication is basically through a series of adverts whenever one goes to the website of Amazon. Amazon has positioned the Kindle as a book carrier for the people on the go. The product is marketed heavily in A merica and not so much in Europe as books have an aesthetic value in the Europe. It considers book as a form of art which is not a case with Americans. Methodology The methodology consists of both the primary and secondary research methodology. The basic aim of the methodology is to gauge the consumer perception of the Amazon Kindle and to analyze the gap between the Brand identity portrayed by the product and the brand image which is actually created in the mind of the consumer of an Amazon Kindle. Generally, it is seen that a new product has problems filling this gap and it is one of the major threat whenever the product is launched in the market. There is a need for the company to portray itself in a manner that the gap is minimized. In order to see the success of the Kindle we tried to visit the various blogs and the website of the Kindle to look for the consumer perception and the post purchase analysis. This methodology was validated by the questionnaire floated on various internet sites and the blogs in order to get maximum responses from the people. The scope of study was narrowed down on to finally three types of units: Users of Amazon Kindle Non-Users of Amazon Kindle People who havent heard of Amazon Kindle It is very important to gauge all the three responses in order to get the birds eye view on the product and the concept delivery. While hundreds of responses were analyzed in the secondary research, we came up with 54 responses in the primary research which was covering the geographical areas of USA, India, France, Germany, Greece, Australia, South Africa, Spain, Argentina and many more nations which make the study geographically significant. The responses were analyzed by the statistical tools such as excel and SPSS in order to come up with the impact analysis of Amazon Kindle and finally the recommendations that we came up to make this process of marketing the Kindle much more efficient and focused. Observations and analysis Secondary research observations: The secondary research was performed on the following web blogs and websites: inventorspot.com ireaderreview.com www.wired.com www.bestebookreaders.com reviews.cnet.com crunchbase.com blogs.techrepublic.com www.computerworld.com wiki.mobileread.com www.hanselman.com www.macworld.com gadgets.boingboing.net arstechnica.com www.digitaltrends.com Amazons Website The blogs are the major technology blogs which constantly receive the comments of the users and the non users and are a fair indicator of the trends and perception of the new product in the market. This is majorly significant in the case of the Kindle as the marketing mix of the product significantly enhances the importance of the blogs and reviews online. The product is sold online only and thus all the users or the people who are interested in the product are more likely to be avid internet users. The first step for adaptation of any new product is the search of the information about the product and the information, in case of Amazon kindle is majorly available on these websites and the Amazons site. The user therefore pays a lot more attention to these blogs in this case. Thus these blogs are very powerful in forming the perception about a product which is sold online. The E-Paper screen is slightly smaller than that on its primary competitor, the Sony Reader, but is still quite legible and roomy E-Paper has a long way to go before it replaces ink on paper, but its comfortably on the right path Youll need to use the Kindle in the same sort of well-lit environment that youd read a normal book or magazine Some of the features such as the expandable memory and the wireless services truly make using a Kindle an unforgettable experience. However, we can never call the Kindle a radical innovation as the concept was already put in to the market by Sony via their Sony reader. But as compared to its counterparts, it is perceived as a pioneer in innovation and technology. With the latest launch of the I-PAD, there has been a lot of speculation while we compare the I-PAD to the Kindle. While both Apple and Amazon maintain that the products are not in competition but there has always been a comparison made which can be unfair to the Kindle as it is not a multipurpose device as compared to the Kindle. But Kindle has been very proactive in ensuring that they come out with the subtle innovations that would keep their nose ahead at all times. This can be seen when they launched the Kindle application for the IPAD very recently just after the launch of the IPAD. Primary Research Observations The primary research was conducted on 51 respondents who were spread all over the globe on all continents of the world. The respondents were divided into 3 categories and the perception mapping was performed. The results show high involvement of Americans over the rest of the world. This can be easily explained by the history of the Amazon Kindle which launches the new version in America first and then another version is launched in the rest of the world. There is always an international version of the Kindle which is meant for the rest of the world except America. The research had 61 percent female respondents and 39 percent male respondents. There were many avid readers among the Americans who answered the questionnaire. The total avid readers were 55 percent and out of those, 80 percent were Americans. The value sought in the Amazon Kindle was very high among these groups of people which tell us that the Kindle is very popular among the people who love to read a lot. The people were mainly fond of the fact that the kindle is very compact and easy to operate. The peoples response was mainly hinting that the Kindle is surely a device that they would like to buy but the barriers that they have put either on the initial price and on the subsequent running costs is deterring them from having a Kindle with them. According to them, there is a special place of books in there and Amazon should not compete with them. The testimony of the fact is that the 90 percent of the people preferred paperback books instead of an electronic book if given a free choice. The reason given is that the book looks much more real and there is a sense of possession when we have a book in our hand rather than when we have an eBook in our laptops of our Kindle for that matter. The Kindle had the biggest advantage over the rest of its competitors due to its wireless capabilities which actually allow you to get your favorite books within a few seconds room anywhere in the world and anytime in the world. While Americans and Australians preferred the Kindle because it saved a lot of shelf space which in other cases would have been taken by the books, the Europeans preferred Kindle because it was su pposed to save a lot of paper and it looked elegant in the hand of the possessor. Some of the other findings include the fact that while 39 percent of the respondents were actually Kindle users, there were 21 percent of the respondents who were not aware of the Kindle at all. The reason that we could thought of was that it has something to do with the less popularity of Amazon in the countries of these people as most of these people were from India(50 percent) and Thailand and other parts of Asia. This throws light on the fact that for a product which mainly sells from the internet, it is very important for the parent company to have an established base of consumers who can then communicate with them and participate in the offerings given to them in the form of products such as the Kindle. There is no distribution channel where we can push the product. The other respondents who had heard of the Kindle but never thought of buying it thought that the price of the Kindle is the major factor that deters them from even thinking of having one. For the ones who want to b uy it and do not have it as of now, the major reason is that the people associate a lot of hidden costs with the product. This was a major finding as the company never projects the actual cost to consumer throughout the life of the consumers. While the possessors liked the fact that the Kindle has good connectivity which we too found out as the point of difference of the Kindle from its competitors, the non users liked the read without glare feature the most attractive one. This lead us to one more observation that the most attractive feature is not the unique feature of the kindle so the Kindle may or may not be the first choice of the people when they go on to buy an eBook reader. This is kind of disheartening for the company as the product is highly placed on the price and the technology table and the users may not find value for money once they look to buy a Kindle. There were some serious observations made in the value that the consumers attach regarding the price of the Kindle and that comes out to be around 140 Euros that is way less than the actual price of the kindle i.e. 250 Euros. This leads us to the observations is that the barrier is too high for a large amount of potential users which can be exploited if they agree to lower the initial cost. The people were very apprehensive of the actual cost to customer and Amazon can do well to enlighten the customers about the same. Success of the product to date The Amazon kindle is unarguably the best selling product for Amazon and the adverts on the website of Amazon are a testimony of this. It is the most wished for, most desired and most searched for product on Amazon site which tells us that the product is doing very well on the international scene as well. Some of the factual data released by Amazon can also be seen below. It tells us that the product is doing wonderfully well on the international scene. The product is a very successful one and the continual improvements that it has come up with are a major factor contributing towards such a success. The revenue percentage of Amazon is as high as 2.6 percent that tells us that it is the star performer for Amazon. The fact that is not taken into consideration is that there are huge running costs that are related to each Kindle that are unfortunately not mentioned in the data. But it is clear that the Kindle is doing cery well in the market since its launch in 2008. Recommendations Amazon should focus on advertising to attract new customers to the e-book market. A large potential for growth in its base of consumers is with commuters and business travellers, who will benefit from the convenience of the Kindles portability and also possess the disposable income to afford the device in its current price range. As Ron Hawkins, vice president for portable reader systems at rival Sony, points out, Digital readers are not a replacement for a print book; they are a replacement for a stack of print books. That is where we see people, on the go, in the subway and in airports, with our device. The Kindle delivers newspapers directly to users for, on average, $10/month. This enables commuters to easily read the newspaper on a smaller medium without the unwieldiness of the print version. Similarly, businessmen will find the Kindle appealing to avoid carrying multiple books while travelling. By targeting these consumers through increased advertising in subways, airports, and on airplanes, Amazon can expand the market and reach out to new adopters of e-books. In coordination with this advertising effort, Amazon should attempt to negotiate deals with major newspapers. At a time when newspapers are struggling with declining numbers in readers and revenue, Amazon can seek to capitalize on their situation. For example, the LA Times started a task known as the Manhattan Project seeking to investigate solutions to reinvent the paper for the future. Amazon has the opportunity to approach them with the Kindle as a new venue to revive their business through a younger tech-savvy audience. The primary goal of this advertising campaign is to increase the overall e-book market, rather than to steal customers from rivals, so competitors should not feel threatened by it. In fact, other firms may benefit from the increased awareness of e-book readers. Similarly, parallel campaigns by rivals do not pose a significant threat to Amazon, since the major challenge at hand is to grow the market and provide for future profitability. However, Amazon needs to ensure that rivals do not enter into exclusive contracts with newspapers or other content providers in general. These deals only serve to benefit individual firms in the short run and ultimately hinder expansion of a relatively small, nascent market. Long Term Positioning In the long run the market for e-books themselves is unlikely to support significant profits. The main issue stems from the large amount of publisher bargaining power that currently exists in the print book market. Publishers have a significant influence in the supply chain for books, retaining the largest portion of the producer surplus in print media. The retailer only receives a small fraction of the overall profits on the book, so it is presumable that Amazon will face similar difficulty in extracting profits from e-books. In addition, Amazons business model is reproducible and thus their current distribution advantage is not necessarily permanent. Amazons reputation would be their only substantial barrier to new entrants in the e-book sales market. Lastly, competition with free pirated e-books would present problems. Even if Amazon proves more successful than competitors in e-book retailing, as the market grows, piracy will inevitably emerge to erode profits. This has occurred o ver the last decade in the music industry as digital music and the Internet have matured. These pitfalls make it unwise for Amazon to pursue a partnership with a hardware-oriented company like Sony, in which Amazon would limit itself to selling e-book reader content. Instead, Amazon should continue to produce the Kindle itself. Due to the nature of the market, the selection of complements will not distinguish the Kindle from other readers. If Amazon can maintain comparable hardware quality to other manufacturers, switching costs and brand identity should allow Amazon to keep a stable customer base and to support some level of sustainable profits. Pricing It also might be tempting for Amazon to leverage their current advantage in e-book distribution into greater profits on the e-books. This trades larger short term profits for a weaker future position in the market, which will be much larger that it is now. Thus, Amazons pricing strategy should be consistent with the long term focus on hardware and a desire to prioritize market share over short term profits throughout the growth phase. Amazons recent price reduction from $399 to $359 reflects a shift from targeting quality sensitive early adopters to more price sensitive consumers. It should continue to drop prices in steady increments to attract wider consumer bases. Consumers are less sensitive to e-book prices than they are to hardware prices, and the decision to purchase a Kindle is more likely to be triggered by the cost of the Kindle itself. Hence, Amazon should not be overly concerned with further reducing e-book prices. These prices are currently lower than most hardbacks and trade paperbacks but higher than most mass market paperbacks. Attempting to compete with mass market paperbacks is infeasible because of publishers resistance to pricing e-books much cheaper than print versions. It already loses money on most of its e-books, priced well below what it pays publishers, and further price cuts would likely require Amazon to take losses unjustified by the small benefits in market share. However, if the Kindle is able to propel the e-book markets into a fast growing phase, publishing executives anticipate that it will not be long before Amazon begins using the Kindles popularity as a lever to demand that publishers cut prices. At this point , Amazons increased bargaining power will enable it to price more competitively without the losses from subsidies.

Becoming Hero in William Shakespeares Hamlet Essay -- William shakesp

Becoming Hero in William Shakespeare's Hamlet The hero; the most dominant of archetypes throughout time and culture, is represented in the following description of the basic unit of the monomyth by the mythic scholar Joseph Campbell, â€Å" A hero ventures forth from the world of common day into a region of supernatural wonder: fabulous forces are there encountered and a decisive victory is won: the hero comes back from this mysterious adventure with the power to bestow boons on his fellow man." It is in this light that we moderns as well as our ancestors have given life and formation to our universal struggles. By representing the greater tribe, community, country, etc†¦ each story has within it, a character who leads and who undertakes that primordial journey toward a destination that will ultimately restore vitality or provide that elixir to her people, which is so needed. However complex, our world has brought forth several thousand variations on the hero itself, with as many problems and hopes as a people might have, so too does the heroic character of a culture embody them. Yet, as complicated and nuanced and non-traditional a society’s representative hero might be, the character of Hamlet seems to be the most unique in that more than creating an anti-hero who still provides in some way for his people, albeit in a way that bucks societies’ cultural norms, Shakespeare has created his story around a man who destroys rather than builds and a hero who subverts the archetype so much, that the basic tenants of heroic description must be altered in order to recognize him at all for what he seems to be. In the traditions of the hero archetype, the journey of the hero follows a path that can be symbolized by the markers of d... ...es, directed towards him, at which he is powerless to defend. At the burial scene, where Hamlet has unwittingly encountered death, first with the accidental discovery of Yorick, and then with the accidental discovery of Ophelia, he is forced into a plot not of his own doing. By returning from England with thoughts of action and of blood on his mind, he has been placed in the direct pathway of the revenge of Laertes for the death of his father. Used by Claudius, Laertes is imbued with his own hatred as well as the intellectual powers of the King. By juxtaposing Hamlet and Laertes over the grave of Ophelia, Shakespeare has created a scene where Hamlet has lost sight of his true mission again, this time to prove his skills of articulation and of false mourning for his tormented lover, â€Å"Forty thousand brothers Could not, with all their quantity of love, Make up my sum."

Key Cryptography Basics :: Encryption Internet Essays

Key Cryptography Basics Problems with internet transactions As discussed in class there are several problems with internet communication. The major three are: Eavesdropping is the risk of having private information viewed as it travels from sender to recipient by a third party. The most popular fear is having your credit card number and information stolen while purchasing something online, but this would apply to any private information delivered over the internet. Tampering is the risk of a third party intercepting a private transaction of information and changing it. An example of this would be altering the recipient fields on a purchase order. Impersonation is the risk of someone impersonating a trusted recipient in order to receive private information. This Encryption Cryptograms in the newspaper are probably one of the most basic forms of encryption. A simple system of swapping letters for other letters is used to disguise the message making it indistinguishable to anyone who does not know the rules of the system. Even though the cryptogram system is so simplistic it is actually considered sporting to crack, the basic logic of encoding is the same for more sophisticated methods. Key Based Encryption (symmetric encryption) In this example of Key based encryption we first create a number conversion table so that we can apply mathematical rules to our message after converting it. Number Conversion Table: a b C d e f g h i j k l m 1 2 3 4 5 6 7 8 9 10 11 12 13 n o P q r s T u v w x y z Space 14 15 16 17 18 19 20 21 22 23 24 25 26 0 Then we decide upon a key. In order to decipher this code the recipient will also be required to posses this key. It will become obvious by the end of our example that the shorter the key the easier the code will be to crack. Key: Encrypted We then take the message and the key convert them using the conversion table and add them together. Then in order to reassign them to a letter value we take the mod base 27 in order to restrict the letter assignment to numbers within the 0 to 27 table. Message: on the internet nobody knows you are a dog

To Kill a Mockingbird by Harper Lee :: To Kill a Mockingbird Essays

A summary: When Scout was six, Dill (Charles Baker Harris) comes to visit his aunt and becomes good friends with the Finches. The children in Maycomb spend all their free time of summer trying to get Boo (Arthur) Radley come out of his house. None of the children have ever seen the mysterious man that lives next door, but they never find out that he is actually shut up in this house. After the summer is over, Scout enters school and gets into trouble because she already knows how to read and to write. She is always constantly getting into fights with boys like Walter Cunningham, the son of a poor farmer. During that year, Scout and her older brother Jem begin to find things in a hole in a tree on the Radley property as they pass it going to and from school. The next summer, Dill returns and the three continue their plans to make Boo Radley emerge from his house. They try to use a fishing pole to stick a note onto one of the windows of the Radleys. One night they decided to sneak up t o one of the windows to have a peek inside. Jem reaches the porch when a shadow appears and the three of them run for their lives just as a shotgun blast is heard. Jem gets caught on the fence by his pants so he has to slip out of them in order to escape. Later he tries to go get the pants that he lost and is afraid. A little bit later Scout hears that the pants were mended very strangely and lying on the fence. The next fall, the children make their first snowman. During this cold spell, Miss Maudie's house burns down and Scout and Jem have to stand outside for fear that their house might also burn down. While they are shivering in the cold, someone wraps a blanket around scout without their knowing it. All indications point to Boo Radley putting the blanket around her. About this time, the children begin to hear in the town that their father is a "nigger- lover." Atticus warns his children never to fight about this, but at Christmas time when one of Scout's cousins makes the same statement, she bloodies his nose. That Christmas, both children receive air rifles but they are given instructions that they must never kill a

7) Data from a small bookstore are shown in the accompanying table. The manager wants to predict Sales from Number of Sales People Working. Number of sales people working| Sales (in $1000)| 4| 12| 5| 13| 8| 15| 10| 16| 12| 20| 12| 22| 14| 22| 16| 25| 18| 25| 20| 28| x=11. 9| y=19. 8| SD(x)=5. 30| SD(y)=5. 53| a) Find the slope estimate, b1. Use technology or the formula below to find the slope. b1=rsysx Enter x,y Data in TI-84 under STAT > STAT > CALC > 8: LinReg(a+bx) b1=1. 023 b) What does b1 mean, in this context?The slope tells how the response variable hanges for a one unit step in the predictor Thus, an additional; $1,023 of sales associated with each additional sales person working. c) Find the intercept, b0. b0=y-b1x =19. 8-1. 023(11. 9) For this problem, use technology, rounding to three decimal places. b0=7. 622 d) What does b0 mean in this contet? Is it meanful? The intercept serves as a starting value for the predicitons. It shuld only be interpreted if a 0 value for the predictor variable makes sense for the context of the situation. On average, $7,622 is expected when 0 sales people are working.It is not meaningful because it does not make sense in this context. e) Write the equation that predicts Sales from Number of Sales People Working. Recall that the slope of the equation b1=1. 023 and the intercept is b0=7. 622 Complete the equation. Sales=7. 622+1. 023 *(Number of Sales People Working) f) If 19 people are working, what sales do you predict? Substitute 19 for the number of sales people working in the equation found in the previous step and solve for Sales. Sales=7. 622+1. 023 *(Number of Sales People Working) =7. 622+1. 023*19Substitute. =27. 059Simplify. *Note that each unit of Sales represents $1000. Thus, the predicted sales for 19 people working is 27,059 dollars. g) If sales are actually $26,000, what is the value of the residual? Subtract the predicated value found in the previous step from the actual value. 26,000-27,059=-1059 Thus, t he value of the residual is -1059 dollars. h) Have the sale been overestimated or underestimated The predicted sales are $27,059 and the actual sales are $26,000. Since $27,059 > $26,000, the sales were overestimated. 13) Of the 46 individuals who responded, 25 are concerned, and 21 are not concerned. of those concerned about security are male and 5 of those not concerned are male. If a respondent is selected at random, find each of the fallowing conditional probabilities. | Male| Female| Total| Concerned| 9| 16| 25| Not Concerned| 5| 16| 21| Total| 14| 32| 46| a) The respondent is male, given that the respondent is not concerned about security. P(Male|Not Concerned) = 521 = 0. 238 b) The respondent is not concerned about security, given that is female P(Not Concered|Female) = 1632 = 0. 500 c) The respondent is female, given that the respondent is concerned about security. P(Female|Concerned) = 1625 = 0. 40 14) It was found that 76% of the population were infected with a virus, 21% were without clean water, and 18% were infected and without clean water | Clean Water| | | Yes| No| Total| Infected| 0. 58| 0. 18| 0. 76| Not Infected| 0. 21| 0. 03| 0. 24| Total| 0. 79| 0. 21| 1. 00| a) What’s the probability that a surveyed person had clean water and was not infected? .21 had clean water and was not infected 15) A survey concluded that 54. 4% of the households in a particular country have both a landline and a cell phone, 32. 6% have only cell phone services but no landline, and 4. 6% have no telephone services at all. ) What proportion of households have a landline? Begin by making a contingency table. | Cell Phone| | | Yes| No| Total| Landline| 0. 545| 0. 083| 0. 628| No Landline| 0. 326| 0. 046| 0. 372| Total| 0. 871| 0. 129| 1. 00| The completed contingency tables shows that P(landline) = 0. 628. b) Are having a cell phone and having a landline independent? Explain. Events A and B are independent when P(B|A) = P(B). To determine wheter having a cell pho ne and having a landline are indepented, find P(landline|cell phone) and P(landline). Recall from part a) that P(landline) =0. 628 PBA=P(A and B)P(A)Use the formula to find P(landline|cell phone) Plandlinecell phone=P(landline and cell phone)P(cell phone) Since the contingency table shows that P(landline and cell phone)=0. 545 and P(cell phone)=0. 871, substitute these values into the equation. Divide to find the conditional probability, rounding to three decimal places. Plandlinecell phone=0. 5450. 871=0. 626 Thus, P(landline|cell phone)=0. 626 and P(landline)=0. 628. Because 0. 626 is very close to 0. 628, having a cell phone and having a landline are probably independent. Of the households surveyed, 62. 6% with cell phones had landlines, and 62. 8% of all households did. 6) A marketing agency has developed three vacation packages to promote a timeshare plan at a new resort. They estimate that 30% of potential customers will choose the Day Plan, which does not include overnight ac commodations; 30% will choose the Overnight Plan, which includes one night at the resort; and 40% will choose the Weekend Plan, which includes two nights. a) Find the expected value of the number of nights that potential customers will need Vacation Package| Nights Included| Probability P(X=x)| | Day Plan| 0| 30100=0. 3| | Overnight Plan| 1| 30100=0. 3| | Weekend Plan| 2| 40100=0. 4| | This, P(X=0)=0. 3, P(X=1) =0. 3, and P(X=2)=0. Use the formula E(X) = ? x †¢ P(x) to detrime the expected value. E(X) = ? x †¢ P(x) = 0(0. 3) +1(0. 3) +2(0. 4) = 1. 1 There, the expected value of the number of night potential customers will need is 1. 1 b) Find the standard deviation of the number of nights potential customers will need. The standard deviation is the square root of the variance. First, Find the Variance: To do so, find the deviation of each value of X from the mean and square each deviation. The variance is the expected value of these squared deviations and is found using th e formula below. = Var(X) = ? (x –  µ)? P(x) Find the deviation for each value of X.Remember that E(x)=1. 1 Vacation Package| Nights Included| Probability P(X=x)| Deviation (x – E(X))| Day Plan| 0| 30100=0. 3| 0 – 1. 1 = -1. 1| Overnight Plan| 1| 30100=0. 3| 1 – 1. 1 = -0. 1| Weekend Plan| 2| 40100=0. 4| 2 – 1. 1 = 0. 9| Now find the variance using the formula =Var(X)=? (x –  µ)? P(x) Var(X) = ? (x –  µ)? P(x) = (-1. 1)? (0. 3) + (-0. 1)? (0. 3) + (0. 9)? (0. 4) = 0. 69 Finally, the standard deviation also known as ? is the square root of the variance. ? = Var(x) = 0. 69 = 0. 83 Therefore, the standard deviation of the number of nights potential customers will need is approximately 0. 83 nights. 7) A grocery supplier believes that in a dozen eggs, the mean number of broken eggs is 0. 2 with a standard deviation of 0. 1 eggs. You buy 3 dozen eggs without checking them. a) How many broken eggs do you get? The expected value of t he sum of random variables is the sum of the expected values of each idividula random variable. Find the sum of the expected values where X is the total number of broken eggs in the three dozen, and X, X, X Represent the three individual dozen eggs. E(X) = E(X1) + EX2+ EX3 = 0. 2 + 0. 2 + 0. 2 = 0. 6 Therefore, the expected value of X is 0. 6 eggs. b) What’s the standard deviation?The variance of the sum of independent variables is the sum of their individual variances. Find the variance for each carton, add the variances, and then take the square root of the sum to find the standard deviation. The variance of each individual dozen is the square of each dozens standard deviation. Var(X1) = Var(X2) = Var(X3) = 0. 12= 0. 01 Find the sum of the variances to find the variance of the sum. Var(X) = VarX1+ VarX2+ VarX3 = 0. 01 + 0. 01 + 0. 01 = 0. 03 Recall that the standard deviation is the square root of the variance. Find the standard deviation. SD(X) = Var(x) = 0. 03 = 0. 17Ther efore, the standard deviation is 0. 17 eggs c) What assumptions did you have to make about the eggs in order to answer this question? The variance for the sum of random variables is only the sun of variances of each random variable in certain cases. Review the assumption that must be made to allow the variance to be the sum of the individual variances. 18) An insurance company estimates that it should make an annual profit of $260 on each homeowner’s policy written, with a standard deviation of $6000. a) Why is the standard deviation so large? Home insurance is used to protect the owner financially in the event of a problem.If a catastrophe occurs, then the insurance company will cover the cost of the damage. If a catastrophe never occurs, then the insurance company pays nothing. Meanwhile, the owner pays the insurance company at regular intervals whether or not a catastrophe occurs. The expected value is the mean annual profit on all of the policies and the standard deviatio n is a measure of how much annual profits can differ from the mean. Use this information with the fact that claims are rare, but very costly, occurrences. b) If the company writes only four of these policies, what are the mean and standard deviation of the annual profit?LetX1,X2, X3,†¦,Xn represent the annual profit on the n policies and let X be the random variable for the total annual profit on n polices written. X=X1+X2+ X3+†¦+Xn The expected value of the sum is the sum of the expected values. Find the expected value of the annual profit on each policy. EX1=EX2=EX3=EX4=$260 Now find the sum of the expected values. EX=EX1+EX2+EX3+EX4 =260+260+260+260 = $1040 Therefore, the mean annual profit is $1040 To find the standard deviation of the annual profit, use the fact that te variances of the sum of independent variables is the sum of their individual variances. First find the variance for each policy.The variance for the policy is the square of the standard deviation. VarX 1=VarX2=VarX3=VarX4=60002=36,000,000 VarX=VarX1+VarX2+VarX3+VarX4 = 4(36,000,000) = 144,000,000 Evaluate the square root of the variance to find the standard deviation. SDX=VarX =144,000,000 =$12,000 Therefore, the standard deviation is $12,000 c) If the company writes 10,000 of these policies, what are the mean and standard deviation of annual profit? The expected value of the sum is the sum of the expected values. The expected value of each policy was found earlier. EX1=EX2=EX3=†¦ =EX10,000=$260 Now find the sum of expected values. EX=EX1+EX2+EX3+†¦ +EX10,000 10,000(260) =$2,600,000 Therefore, the mean annual profit is $2,600,000 To find the standard deviation of the annual profit, use the fact that the variance of the sum of independent variables is the sum of their individual variances. First find the variance for each policy. The variance for the policy is the square of the standard deviation and was found earlier. VarX1=VarX2=VarX3= †¦ =VarX10,000=36,000,000 Now sum the variances to find the variances of the sum. VarX=VarX1+VarX2+VarX3+†¦ +VarX10,000 =10,000(36,000,000) =360,000,000,000 Evaluate the square root of the variance to find the standard deviation. SDX=Var(X) =360,000,000,000 $600,000 Therefore, the standard deviation is $600,000. d) Do you think the company is likely to be profitable? Recall that the mean annual profit for 10,000 policies is $2,600,000. While this number seems quite large, it is necessary to determine how likely a profit is to ensure that this company will be profitable. Find the distance in standard deviation of $0 from the mean to determine how rare an occurrence of no profit would be. z=x- =0-2,600,000600,000 =-4. 3 Thus, $0 is 4. 3 standard deviation below the mean. **Note that approximately 95% of the annual profits should lie within two standard deviations of the mean.Evaluate whether the distance of $0 from the mean is convincing enough to determine whether or not the company will be profitable. e) W hat assumptions underlie your analysis? Can you think of circumstances under which those assumptions might be violated? The variance of the sum of random variables is only the sum of the variances of each random variables in certain cases. Review the assumption that must be made to allow the variance to be the sum of the individual variances. Then chose the situation that would create an association among policy losses. 19) A farmer has 130 lbs. of apples and 60 lbs. f potatoes for sale. The market price for apples (per pound) each day is a random variable with a mean of 0. 8 dollars and a standard deviation of 0. 4 dollars. Similarly, for a pound of potatoes, the mean price is 0. 4 dollars and the standard deviation is 0. 2 dollars. It also costs him 5 dollars to bring all the apples and potato’s to the market. The market is busy with shoppers, so assume that he’ll be able to sell all of each type of produce at the day’s price. a) Define your random variables, and use them to express the farmer’s net income. A random variable’s outcome is bases on a random event.Therefore let the random variables represent the factors that will be randomly determined each day. The random variables should represent the market prices of the two items. A = price per pound of apples P = price per pound of potatoes The profit is equal to the total income minus the total cost. The income is found by multiplying the market price for apples by the total number of pounds sold and adding it to the product of the market price for potatoes and the number of pounds of potatoes sold. The total cost is the transparent cost. Profit = 130A + 60P – 5 b) Find the mean. The mean of the net income is the expected value of the profit.Profit = 130A + 60P – 5 E(Proft) = E(130A + 60P – 5) Use the property E(X + Y) = E(X) + E(Y) to express the expected value of the profit as the sum of two separate expected values E=(Profit) = E(130A +60P -5) = E [(130A) + (60P – 5)] = E(130A) + E(60P – 5) Now use the property EX ±c= E(X) ±c E(Profit) = E(130A) + E(60P – 5) = E(130A) + E(60P) – 5 Finally, use the property E(aX) = aE(X) to remove the coefficient from the expected values. E(Profit) = E(130A) + E(60P) – 5 = 130E(A) + 60E(P) – 5 Substitute the known expected values of the prices of apples and potatoes in the equation. E(Profit) = E(130A) + E(60P) – 5 E(0. 8) + E(0. 4) – 5 Evaluate the expected profit. E(Profit) = 130(0. 8) + 60(0. 4) – 5 = 123 Therefore, the mean is 123 dollars. c) Find the standard deviation of the net income. To find the standard deviation, first find the variance and then take the square root, since the properties useful in this case are in terms of variance and not standard deviation SD(Profit) = Var(Profit) = Var(130A+60P-5) First use the property Var(X + Y) = Var(X) + Var(Y) to express the variance of the profit as the sum of two separate v ariance Var(Profit) = Var(130A + 60P – 5) = Var[(130A) + (60P – 5)] =Var(130A) + Var(60P – 5)Now use the property Var(X  ± c) = Var(X) to simplify the second variance Vr(Profit) = Var(130A) + Var(60P – 5) = Var(130A) + Var(60P) Finally, use the property VaraX=a2VarX to restate each variance. Var(Profit) = Var(130A) + Var(60P) = 1302VarA+ 602VarP = 16,900Var(A) + 3600Var(P) Evaluate the variance of the profit. Var(Profit) = 16,900(0. 16) + 3600(0. 04) = 2848 Lastly, find the standard deviation, rounding to two decimal place. SD(Profit) = VarProfit = 2848 = 53. 37 Therefore, the standard deviation of the net income is 53. 37 dollars. d) Do you need to make any assumptions in calculating the mean?Recall that the mean of the sum of two or more random variables is the sum of the means. Determine what, if any, assumptions are made to use this property. Do you need to make any assumptions in calculating the standard deviation? Recall that the variance of the s um of two random variables is only the sum of their individual variances in certain cases, Determine what, if any, assumptions are made to use this property. 20) A salesman normally makes a sale (closes) on 65% of his presentations. Assuming the presentations are independent, find the probability of the following. ) He fails to close for the first time on his sixth attempt. Use the formula below to determine the probability, where p is the probability success, q=1 – p and X is the number of trails until the first success occurs. P(X=x) = qx-1p Find the values for p and q. **Note that in this case that a success is defined as failed to close p = 0. 35 q = 0. 65 Substitute and solve to find P(X=6). Rounding to four decimal places P(X=6) = qx-1p = 0. 656-1(0. 35) = 0. 0406 Therefore, the probability he fails to close for the first tie on his sixth attempt is 0. 0406 b) He closes his first presentation on his fifth attempt.Find the values for p and q. **Note that in this case tha t a success is defined as making a sale p = 0. 65 q = 0. 35 Substitute and solve to find P(X = 5), rounding to four decimal places P(X=5) = qx-1p = 0. 355-1(0. 65) = 0. 0098 Therefore, the probability he closes his first presentation on his fifth attempt is 0. 0098 c) The first presentation he closes will be on his second attempt. Find the values for p and q. Note that in this case that a success is defined as making a sale. p = 0. 65 q = 0. 35 Substitute and solve to find P(X=2) P(X=2) = qx-1p = 0. 352-1(0. 65) = 0. 2275Therefore, the probability the first presentation he closes will be on his second attempt is 0. 2275 d) The first presentation he closes will be on one of his first three attempts. Use the fact that the compliment of an even is equal to 1 – P(X=x) to find the probability. The compliment event is that he will not close a sale on any of his first three attempts. Find the probability that he does not close on his first three attempts, rounding to four decimal pl aces. 0. 353=0. 0429 Subtract from 1 to find the probability the first presentation he closes will be on one of his first three attempts 1 – 0. 429 = 0. 9571 Therefore, the probability the first presentation he closes will be on one of his first three attempts is 0. 9571 21) College students are a major target for advertisements for credit cards. At a university, 73% of students surveyed said that they had opened a new credit card account within the past year. If that percentage is accurate, how many students would you expect to survey before finding one who had not opened a new account in the past year? First check to see that the cells are Bernoulli trials. Trials are Bernoulli if the following three conditions are satisfied. 1.There are only two possible outcomes (called success and failure) for each trial. 2. The probability of success, denoted p, is the same on every trial. (The probability of failure, 1 – p is often denoted q. ) 3. The trials are independent Ther e are only two possible outcomes for each trial because a student either opened a credit card account in the past year or they did not. The probability of success is the same on every trial, based on the percent given in the problem statement. The trails are independent because each student’s response is not dependent on any other student’s response.Thus, the trials of surveying the students are Bernoulli trials. A geometric probability model models how long it will take to achieve the first success in a series of Bernoulli trials. Let X be the number of students that will have to be surveyed before finding the first student who did not open a credit card in the past year. The two outcomes are a student who did not open a credit card account in the past year *success) and a student who opened a credit card account in the past year (failure). The probability of a failure is given in the problem statement as q = 73% = 0. 73.Find the probability of success by subtracting this from 1. P = 1 – 0. 73 = 0. 27 Find the expected value of X. In a geometric model, the expected value is EX= 1p , where p is the probability of success. Round up to the nearest integer. EX=10. 27=4 Therefore, on average, you would expect to survey 4 students before finding one who had not opened a new account in the past year. 22) A certain tennis player makes a successful first serve 82% of the time/ Assume that each serve is independent of the others. If she serves 7 times, what’s the probability she gets a) all 7 serves in? b) exactly 5 serves in? ) at least 5 serves in? d) no more than 5 serves in? The first step is to check to see that these are Bernoulli trails. The first serves can be considered Bernoulli trials. There are only two possible outcomes, successful and unsuccessful. The probability of any first serve being good is given as p = 0. 82. Finally, it is assumed that each serve is independent of the others. Next define the random variable. Each questi on deals with the number of serves, so let X be the number of successful serves in n = 7 first serves. Now determine which probability model is appropriate for these problems.Recall that geometric probability models deal with how long it will take to achieve a success. A binomial probability model describes the number of successes in a specific number of trails. All the question deal with the number of successful serves so the binomial probability model Binom(7,0. 82 is appropriate here. a) all 7 serves in? The probability that she ges all 7 serves in is P(X=7). To use the binomial probability model Binom(n,p), use the fallowing formula, where n is the number of trials, p is the probability of success, q is the probability of failure (q = 1 – p), and X is the number of successes in n trials.PX=x= nxpxqn – x, where nx= n! x! n-x! First substitute the correct values into the formula PX=7= 770. 8270. 187- 7 Now simplify. P(X = 7) ? 0. 249 Therefore, the probability that s he gets all 7 serves in is approximately 0. 249 binomPDF(7, . 82, 7) = b) exactly 5 serves in? The probability she gets exactly 5 serves in is P(X = 5). As in part a, use the formula PX=x= nxpxqn – x to find this probability PX=5= 750. 8250. 187 – 5 ?0. 252 Therefore, the probability she gets exactly 5 serves in is approximately 0. 252 binomPDF(7, . 82, 5) = c) at least 5 serves in?To find P(at least 5 serves in), first determine and an expression that is equal to this probability. Note that the wording â€Å"at least 5†, means 5 or more, meaning that there can 5, 6, or 7 serves in. Thus, the probability equals P(X=5) + P(X=6) + P(X=7). So to find the probability that she got at least 5 serves in, evaluate. P(X=5) + P(X=6) + P(X=7) = 75(0. 82)50. 187-5+76(0. 82)6(0. 18)7-6+77(0. 82)7(0. 18)7-7 ?0. 885 Therefore, the probability she gets at least 5 serves in is approximately 0. 885 binomPDF(7, . 82, 5) + binomPDF(7, . 82, 6) + binomPDF(7, . 82, 7) = d) no more th an 5 serves in?To find P(no more than 5), first determine an expression that is equal to this probability. Note that the wondering â€Å"no more than 5† means 5 or less, meaning that there can be 0 thru 5 successful serves. Thus, the probability equals P(X? 5). So to find the probability that there are no more than 5 serves in, evaluate P(X? 5), which is equal to P(X=0) + P(X=1) + †¦ + P(X=5), using the formula PX=x= nxpxqn – x P(X=0) + P(X=1) + †¦ + P(X=5) = 70(0. 82)00. 187-0+71(0. 82)1(0. 18)7-1 + †¦ + 75(0. 82)5(0. 18)7-5 ? 0. 368 Therefore, the probability that there are no more than 5 serves in is approximately 0. 368 binomCDF(7, . 82, 5)
