Investigate the distribution of malesacute; and/ or females in families Essay Example Investigate the distribution of malesacute; and/ or females in families Essay Investigate the distribution of malesacute; and/ or females in families Essay It states: Investigate the distribution of malesà ¯Ã‚ ¿Ã‚ ½ and/ or females in families. You may choose, for example, to collect data on the distribution of girls in families of three children and to estimate the probability of a female birth. To be able to collect the necessary data for the investigation, I will have to look at families with 3 children. The datum will be collected from pupils in the school I go to. I will collect the data by sending questionnaires to every pupil in the school from year seven (aged 11-12) to year thirteen (aged 17-18) asking them how many children are in there families and how many are male/female. From here the data will be sorted through and only the relevant questionnaires (the ones with three children in their families) will be taken out. A sample size of thirty is thought to be sufficient in this data collection so to collect this number every successful questionnaire was given a number (136 in total). 136 was placed into a graphic calculator which then randomly gave out 30 numbers. It should be noted that the larger the sample size the more reliable the results are likely to be. Hypothesis: The probability of having a boy in a three-child family is above 75 %. The probability of giving birth to a boy is the same as a girl, this can be proved by using genetic code which is below. x y Boy xy x xx xy When these two are mixed there are 4 out comes: Girl xx x xy xx As the probability of a boy and girl has been proved equal a suitable probability model can be chosen. The most suitable model is the binomial probability model. It is also suitable because the probability of giving birth is independent; this means one event is not dependent on the other. In the instance of giving birth it means that if a mother has already had a boy the chances of having another one are exactly the same as if she had given birth to none. The Binomial Model The binomial model must be set so that the probability of having a boy is 0.5 and the probability of having a girl is set at 0.5. The number of times that the event must happen is 3. The binomial model below is an example of how the final model will look it is possible from this to see how the mathematics are carried and set out. N how many times the event happens R Outcomes from the events P The probability of the outcome Using the results that will be obtained from the binomial model it will be possible to calculate the amount of families out of the 30 collected that should have 3 boys, 3 girls, 1 boy 2 girls or 2 boys 3 girls. The 4 binomial models are below: 1 (no boys) 2 (one boy) 3 (two boys) 4 (three boys) Results to Questionnaires Number selected Amount of children in family Amount of boys Amount of girls 1 3 2 1 2 3 2 1 3 3 1 2 4 3 1 2 5 3 1 2 6 3 2 1 7 3 1 2 8 3 2 1 9 3 2 1 10 3 2 1 11 3 1 2 12 3 1 2 13 3 2 1 14 3 2 1 15 3 3 0 16 3 1 2 17 3 0 3 18 3 2 1 19 3 1 2 20 3 3 0 21 3 3 0 22 3 1 2 23 3 2 1 24 3 2 1 25 3 1 2 26 3 0 3 27 3 1 2 28 3 3 0 29 3 2 1 30 3 0 3 Total families questioned Amount of children in family Total male(Possible 90) Total female(Possible 90) 30 30 47 43 What the results show From the data collected it is possible to see that out of the 30 families questioned, four families had three boys, and three families had three girls, 12 families had two boys and one girl and eleven families had two girls and one boy Below is a probability table showing how the children in the families were distributed Number of boys 0 1 2 3 Probability p(X) 0.1 0.366 0.4 0.133 When this is compared to the binomial probability table the results are very similar. Binomial probability table Number of boys 0 1 2 3 Probability p(X) 0.125 0.375 0.375 0.125 Comparing the real lie results to the binomials model shows a very strong correlation. This seems to prove that the odds of giving birth to a boy is the same as a girl, the results also prove that giving to a boy is independent of any births the mother may have had before. Looking at both sets of results it is possible to calculate the probability of having one or more boys in a family of three children. To work out the probability of having on or more boys in a family the probabilities of having one, two or three boys in a family must be added together. Below is the working for the real life and binomial probabilities. Real world 0.366 + 0.4 + 0.133 = 0.899 Binomial 0.375 + 0.375 + 0.125 = 0.875 Therefore it is possible to conclude that the real world model and the binomial show a strong correlation and therefore proving the original hypothesis. They prove that there is not only a higher than 75% chance of having a boy in three but that there is actually a chance of almost 90%

Poe uses dark words and images of death like â€Å"a mask of black silk† worn by Montresor and â€Å"the damp ground of the catacombs† that both men see as they descend to the vaults (Poe, â€Å"The Cask of Amontillado†). In fact, the phrase â€Å"mask of black silk† and the word â€Å"catacombs† do not only foreshadow Fortunato’s death but also somehow symbolize death itself. The â€Å"mask of black silk† in particular, which is likened to the mask of an executioner, somehow signifies beginning of the initiation rite. Another form of symbolic imagery employed by Poe includes the family coat of arms of the Montresors: â€Å"the foot crushes a serpent rampant whose fangs are imbedded in the heel† (Poe, â€Å"The Cask†). The purpose of this particular form of imagery is to show the reader tha t the theme of death is perfectly intertwined with the theme of revenge and punishment. On the other hand, in â€Å"The Tell-Tale Heart,† it was a disease that â€Å"had sharpened [the narrator’s] senses and that makes him â€Å"very, very dreadfully nervous† that has actually made him kill the old man. Moreover, the narrator seems to have admitted the murder and justifies it only on the basis of impulse. In short, unlike Montresor in â€Å"The Cask of Amontillado,† the narrator in â€Å"The Tell-Tale Heart† does not hold a grudge against his victim although he kills him: â€Å"it was not the old man who vexed me, but his Evil Eye† (Poe, â€Å"The Tell-Tale Heart†). This particular disease that somehow sharpens the narrator’s senses has somehow made him too nervous and too afraid of the old man’s Evil Eye and that is the reason why the narrator smothers the latter with a bed or a pillow until his death. He then chops of f the old man’s head and limbs and hides them under the planks. Although

The Impact of Restoration Comedy on Theatre :: European History

The Impact of Restoration Comedy on Theatre Shortly after the glory days of Elizabethan and Jacobean theatre, a Puritanical movement led by Oliver Cromwell gained control of Parliament. Cromwell ethics did not extend to cover the moral extravagance of theatre. Under the guise of public health and safety, Parliament ordered the closing of all theatres on September 2, 1642. Such dirty public areas were the perfect breeding ground for the spreading of plague. Actors were left with two options, join Charles I in the civil war against Cromwell, or defy the law and continue performing. Then, in 1649, Charles lost his head, establishing the new Commonwealth. In 1653, Cromwell disbanded Parliament and named himself Lord High Protector. During these days of political chaos, a new underground theater evolved. This new theatre was an extremely risky venture. Any actor caught performing would be imprisoned. Box office receipts would be confiscated for the Commonwealth. Enormous fines would be levied against any daring to sit in an audience. Entire playhouses would be destroyed, their interiors gutted or exteriors burned. Theatre faced extinction. It became an obsequious art, catering to Cromwell's strict moral code. Killigrew would survive, and eventually form the Theatre Royal, but he lived in constant fear. Davenant worked through legal channels to produce theatre Cromwell could not dispute. His pieces were simple, more opera then play, and propaganda for the Commonwealth. Interestingly, the first woman to appear on the British stage did so in this time, in Davenant's The Siege of Rhodes. He began pushing the envelope, uncomfortable in his new sycophantic role. He renewed his ties to the British aristocracy, exiled to France. He befriended Charles II, and when the young king made his triu mphant return to power, Davenant was given the monopoly on all theatre in London. He shared this power with his old friend Thomas Killigrew. Under their guidance, the theatre exploded back into being. Those who had remained in England during the Commonwealth had faced years of strict moral repression. Those who fled to France had acquired some of the decadence bred across the channel. In combination, these two forces created a nation of wealthy, witty, amoral hedonists. Their theatre reflected their lifestyles. Thus was born the Restoration Tragedy and the Comedy of Manners. The tragedies were broad, sweeping tales of great heroism. The aristocracy liked to picture themselves in these far off lands, being oh so noble and eloquent.

Are Mobile Phones a Necessity?

Mobile phones take a big part in our lifes nowadays. Although they are very useful, some people are beginning to ask if they are good for us or we really need them. In my opinion, we can’t talk about an easy life without mobile phone. In the first place, as their reason to be invented, we can connect with other people whenever and wherever we want. We can send messages to people and sometimes it can be very important. Especially at deathlines your saviors are mobile phones. Furthermore, as technology is improved, we can do more than just sending messages or talking with someone with mobile phones. We can save our files, listen music and we can connect to internet. We can receive and share a lot of things. And mobile phones’ cameras are very improved, we can catch very good scenes from life†¦ Nevertheles, there are so many people who say that mobile phones are making our lifes â€Å"short†. I mean mobile phones have a weak point: Radition. As many doctors say, mobile phones spread radition, which can be very dangerous for human life. Also, people say that mobile phones kill face to face relationship, basically people do not go to see their relatives, just call them. All in all, despite their weak points, mobile phones are making the life easier. I believe in future radition problem will be solved and mobiles phones will be exactly safe. And we have not to forget this: People make inventions good or bad†¦

Remarque s The Trenches On The Front Lines From The...

The realism, grisly detail, and irony Remarque injects his story of WWII in the trenches on the front lines from the German perspective somehow remains poetic because of his lyrical writing style. Nineteenth century society was not ready for Remarque’s new language of war. Until this novel society held the illusion of war as both glorious and romantic. The idea of such a thing traces back to the ancient Spartans carrying forth to 19th century Europe (Traver 2002). Before Chapter One, Remarque introduces the idea of the ensuing pages are the work of a new language about war. â€Å"This book is to be neither an accusation nor a confession, and least of all an adventure, for death is not an adventure to those who stand face to face with it. It will try simply to tell of a generation of men who, even though they may have escaped its shells, were destroyed by the war† (Remarque Preface). The Significance of the Epigraph As the epigraph to the novel introduces Remarque’s intention of writing the novel he dispenses with the familiar elements of excitement and romance thus favoring a stark and entirely unsentimental read. His language of war becomes an advocate for soldiers who meet death face to face finding war is not an adventure. It is this message about death that Remarque succeeds in his poetic fashion expressing his ideas engaging the reader into the crux of his message about the evil of and written in his own language.
