Concept explainers
Ivy League schools receive many applications, but only some can be accepted. At the schools listed in
Table 11.22, two types of applications are accepted: regular and early decision.
Application Type Accepted | Brown | Columbia | Cornell | Dartmouth | Penn | Yale |
Regular | 2,115 | 1,792 | 5,306 | 1,734 | 2,685 | 1,245 |
Early Decision | 577 | 627 | 1,228 | 444 | 1,195 | 761 |
Table 11.22
We want to know if the number of regular applications accepted follows the same distribution as the number of early
applications accepted. State the null and alternative hypotheses, the degrees of freedom and the test statistic, sketch the
graph of the p-value, and draw a conclusion about the test of homogeneity.
