Question

Quizplus · Accepted Answer

The rejection region is chosen based on the significance level of the test, which is denoted by α. The significance level represents the maximum probability of rejecting the null hypothesis when it is actually true. Therefore, the probability of the test statistic falling into the rejection region, if H0 is true, is equal to α.
