In order to compare the proportions, p1 and p2, of adults age 25 years or older that have college degrees in two different populations, independent random samples, each containing 200 participants, are selected from each population, with the following results:
Conduct a test of hypothesis to determine whether the proportion p1 of adults age 25 or older that have college degrees in population 1 is greater than the proportion p2 of adults age 25 or older that have college degrees in population 2. Use α = .05.
