Textbook Question
Chapter R, Problem 1.23RE
Sample A study in South Africa focusing on the impact of health insurance identified 1590 children at birth and then sought to conduct follow-up health studies 5 years later. Only 416 of the original group participated in the 5-year follow- up study. This made researchers concerned that the follow-up group might not accurately resemble the total group in terms of health insurance. The following table summarizes the two groups by race and by presence of medical insurance when the child was born. Carefully explain how this study demonstrates Simpson’s paradox. (Birth to Ten Study, Medical Research Council, South Africa)

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)).
