An employment information service claims the mean annual pay for full-time male workers over age 25 without a high school diploma is $22,275. The annual pay for a random sample of 10 full-time male workers over age 25 without a high school diploma is listed. At a = 0.10, test the claim that the mean salary is $22,275. Assume the population is normally distributed. 20,656 21,130 22,355 21,391 22,974 16,914 19,154 23,191 24,189 26,286 (c) Find the standardized test statistic. t= (Round to two decimal places as needed.) (d) Decide whether to reject or fail to reject the null hypothesis. O A. Fail to reject H, because the test statistic is not in the rejection region. O B. Fail to reject Ho because the test statistic is in the rejection region. OC. Reject Ho because the test statistic is in the rejection region. O D. Reject H, because the test statistic is not in the rejection region. (e) Interpret the decision in the context of the original claim. O A. There is not sufficient evidence to reject the claim that the mean salary is not $22,275. O B. There is sufficient evidence to reject the claim that the mean salary is $22,275. O C. There is not sufficient evidence to reject the claim that the mean salary is $22,275.
