Question

Consider the following null and alternative hypotheses: H_o: 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 indicates that the population mean is greater than 67, which means we are only interested in the right tail of the distribution. Therefore, it is a one-tailed test with a rejection area in the right tail.
