The author of an introductory textbook on business statistics completed a study using 30 undergraduate statistics students selected at random from a large university. The students were given a comprehensive test that took them an average of 90 minutes to complete with a sample standard deviation of 15 minutes.

Excerpt from 1984
Power is not a means; it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship. The object of persecution is persecution. The object of torture is torture. The object of power is power.
Excerpt from "Shooting an Elephant"
In Moulmein, in lower Burma, I was hated by large numbers of people – the only time in my life that I have been important enough for this to happen to me. I was sub-divisional police officer of the town, and in an aimless, petty kind of way anti-European feeling was very bitter.

Critical Question: What are the descriptive assumptions? find important assumptions made by the author. first to determine the conclusion and the reasons.
Passage: Should it be legal for newspaper and television reporters to refuse to reveal their confidential sources? Indeed it should. The reporter-informant relationship is, after all, similar to those of priest and penitent, lawyer and client, physician and patient---all of which have a degree of privacy under the law. Moreover, if that relationship were not protected, the sources of information needed by the public would dry up.

Douglas Adams (1952–2001), author of The Hitchhiker’s Guide to the Galaxy, compared humans to a puddle of water as a way of illustrating anthropocentric thinking, or what he called “the vain conceit” of humans.
He wrote: "Imagine a puddle waking up one morning and thinking, “This is an interesting world I find myself in, an interesting hole I find myself in. It fits me rather neatly, doesn’t it? In fact, it fits me staggeringly well. It must have been made to have me in it.” Even as the sun comes out and the puddle gets smaller, it still frantically hangs on to the idea that everything is going to be all right; that the world was made for it since it is so well suited to it."

X is an independent standard uniform random variable X ∼ Uniform(0, 1)
Y is an independent standard uniform random variable Y ∼ Uniform(0, 1)
U = min(X, Y )
V = max(X, Y )
Find the correlation coefficient of V and U , ρ(U, V) = Correlation(U, V).
