Quizplus · Accepted Answer

The critical values z $\alpha$ or z $\alpha$  / 2 are the boundary values that define the rejection region(s) for a hypothesis test. The rejection region is the area in the tails of the sampling distribution where the test statistic falls when the null hypothesis is rejected.
