The critical values zα or zα_{/ 2} are the boundary values for: A)the rejection region(s). B)the level of significance. C)Type I error. D)Type II error.

Question

Quizplus · Accepted Answer

The critical values zα or zα_{/ 2} are the boundary values for the rejection region(s) in hypothesis testing. They represent the extreme values of the test statistic that would lead to rejecting the null hypothesis at the chosen level of significance. Therefore, option A is the correct answer. The level of significance (option B) is determined before the critical values are calculated, and Type I and II errors (options C and D) are related to the conclusions drawn from the hypothesis test, rather than the critical values themselves.
