The z-test using rejection region(s) is used when the population is not normal. The z-test using a P-value is used when the population is normal. OB. The z-test using rejection region(s) is used when the population is normal. The z-test using a P-value is used when the population is not normal. OC. In the z-test using rejection region(s), the test statistic is compared with the level of significance a. The z-test using a P-value compares the P-value with the critical values. QD. In the z-test using rejection region(s), the test statistic is compared with critical values. The z-test using a P-value compares the PI-value with the level of significance a.
