In order to test the hypotheses H₀: μ ≤ 100 and H_a: μ 100 at an α level of significance, the null hypothesis will be rejected if the test statistic z is _____. A) ≥ zα B)

Question

In order to test the hypotheses H₀: μ ≤ 100 and H_a: μ > 100 at an α level of significance, the null hypothesis will be rejected if the test statistic z is _____. A) ≥ zα B) < zα C) ≤ -zα D) < 100

Quizplus · Accepted Answer

Since the alternative hypothesis is one-tailed (μ > 100), the rejection region is in the upper tail. Therefore, we reject the null hypothesis if the test statistic z is greater than or equal to the critical value zα.
