Question

In order to test the following hypotheses at an α level of significance
H₀: μ

In order to test the following hypotheses at an α level of significance H<sub>0</sub>: μ 800 H<sub>a</sub>: μ > 800 The null hypothesis will be rejected, if the test statistic z is A) zα. B) < z<sub>α</sub>. C) < -z<sub>α</sub>. D) = α.

800
H_a: μ > 800

The null hypothesis will be rejected, if the test statistic z is

Quizplus · Accepted Answer

Since the alternative hypothesis is μ > 800, we are looking for a large positive test statistic. Therefore, the null hypothesis will be rejected if the test statistic z is greater than the critical value zα (option A).
