Within a population, the differences that exist from
one person to another are often called diversity.
Researchers comparing cognitive skills for younger
adults and older adults, typically find greater differences
(greater diversity) in the older
population (Morse, 1993) Following are typical data showing
problem-solving scores
for two groups of participants.

Using the methods in Section 11.1, test the hypothesis (α =
0.05) that the population proportions of red and brown are equal
(pred = pbrown). You are testing if their proportions are equal to
one another. NOTE: These are NOT independent samples, but we will
use this approach anyway to practice the method. This also means
that n1 and n2 will both be the total number of candies in all the
bags. The “x” values for red and brown are...
