1. A researcher is interested in finding out if college-bound high school students tend to smoke cigarettes less than high school students who are not college-bound. He distributes a questionnaire and finds that for a group of 57 college-bound students, the mean number of cigarettes smoked per week is 4.0 with a standard deviation of 2.0. For 36 non-college-bound students, he finds that the mean number of cigarettes smoked per week is 9.0 with a standard deviation of 3.0. A....

A: You recently took a statistics class in a large class with n = 500 students. The instructor tells the class that the scores were Normally distributed, with a mean of 7 2 (out of 100 ) and a standard deviation of 8 , but when you talk to other students in the class, you find out that more than 30 students have scores below 45 . That violates which rule for the Normal distribution? the 30–60–90 rule the 1–2–3...

Suppose that there is a class of n students. Homework is to be returned to students, but the students’ homework assignments have been shuffled and are distributed at random to students. a) Calculate the probability that you get your own homework back. (I think it is 1/n) b) Suppose that I tell you that another student, Betty, got her own homework. Does this change the probability that you get your own homework, and if so what is the new probability?...
