Question

Consider the following null and alternative hypotheses: H₀: µ $\le$ 67 H_a: µ > 67 These hypotheses ___. A) indicate a one-tailed test with a rejection area in the right tail B) indicate a one-tailed test with a rejection area in the left tail C) indicate a two-tailed test D) are established incorrectly E) are not mutually exclusive

Quizplus · Accepted Answer

The alternative hypothesis (H_a: µ > 67) only states that the mean is greater than 67, which indicates a one-tailed test with a rejection area in the right tail. Therefore, the null hypothesis (H₀: µ F1F1F1S1F1F1F10 67) also indicates a one-tailed test with a rejection area in the right tail.
