Quizplus · Accepted Answer

In a two-tailed test for the population mean, the null hypothesis will be rejected at a level of significance of α if the absolute value of the test statistic z is greater than the critical value obtained from the standard normal distribution for the α/2 level of significance (since it is a two-tailed test). Therefore, the correct choice is |z| > z_a/2.
