# Question: Suppose you wish to test a hypothesis that two treatments

Suppose you wish to test a hypothesis that two treatments, A and B, are equivalent against the alternative that the responses for A tend to be larger than those for B.

a. If the number of pairs equals 25, give the rejection region for the large-sample Wilcoxon signed rank test for a = .05.

b. Suppose that T+ = 273. State your test conclusions.

c. Find the p -value for the test and interpret it.
