Textbook Question
Chapter 14.3, Problem 25E
In an investigation of alcohol use among college students, each male student in a sample was categorized both according to age group and according to the number of heavy drinking episodes during the previous 30 days (“Alcohol Use in Students Seeking Primary Care Treatment at University Health Services,” J. of Amer. College Health, 2012: 217–225).
Age Group | ||||
18-20 | 21–23 | ≥24 | ||
# Episodes | None | 357 | 293 | 592 |
1–2 | 218 | 285 | 354 | |
3–4 | 184 | 218 | 185 | |
≥5 | 328 | 331 | 147 |
Does there appear to be an association between extent of binge drinking and age group in the population from which the sample was selected? Carry out a test of hypotheses at significance level .01.

5. Let X and Y be independent random variables and let the superscripts denote
symmetrization (recall Sect. 3.6). Show that
(X + Y) X+ys.
8. Suppose that the moments of the random variable X are constant, that is, suppose
that EX" =c for all n ≥ 1, for some constant c. Find the distribution of X.
9. The concentration function of a random variable X is defined as
Qx(h) = sup P(x ≤ X ≤x+h), h>0.
Show that, if X and Y are independent random variables, then
Qx+y (h) min{Qx(h). Qr (h)).
