Zachary completes a hypothesis test and finds that he rejects the null hypothesis. Which statement gives a reason for rejecting the null hypothesis?

A hypothesis test rejects the null hypothesis when its test statistic falls in the critical region, the range of values considered sufficiently unlikely if the null hypothesis were true. The z-statistic’s being positive or negative alone does not determine whether to reject; that depends on the test’s critical region. Therefore, the correct choice is “The z-statistic lies in the critical region.”
