Answer:
D
Step-by-step explanation:
In the z-test using rejection region(s), you determine critical values based on the chosen significance level (alpha), and then compare the calculated test statistic to these critical values. If the test statistic falls within the rejection region (beyond the critical values), you reject the null hypothesis.
In the z-test using a P-value, you calculate the probability (P-value) of observing a test statistic as extreme as, or more extreme than, the one obtained from the sample data. You then compare this P-value to the chosen significance level (alpha). If the P-value is less than or equal to alpha, you reject the null hypothesis.
