Explain the difference between the z-test for μ using rejection region(s) and the z-test for μ using a P-value. Choose the correct answer below. O A. 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. B. 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 P-value with the level of significance a. O C. 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. O D. 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.
