life is different from 7,529 hours. 4. If, in a sample of n = 25 selected from a normal population, X = 59 and S = 15, what is your statistical decision if the level of significance, a is 0.05, the null hypothesis, Ho, is u =50, and the alternative hypothesis, H, , is ul # 50? a. Determine the critical value(s). The critical value(s) is(are) (Round to four decimal places as needed. Use a comma to separate answers as needed.) b. Determine the test statistic, tSTAT. STAT = (Round to four decimal places as needed.) c. State your statistical decision. Choose the correct answer below. A. The test does not reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u = 50. O B. The test rejects the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u = 50. O C. The test rejects the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from u = 50 O D. The test does not reject the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from u = 50. 5. If, in a one-tail hypothesis test where Ho is only rejected in the upper tail, the ZSTAT =-1.01, what is the statistical decision if the null hypothesis is tested at the 0.10 level of significance? a. Compute the p-value for this test. (Round to the nearest four decimal places to the right of the decimal point.) O A. p-value = 2*(1-NORM.S.DIST(-1.01,1)) = 1.688 O B. p-value = 1-NORM.S.DIST(-1.01,1) = 0.8438 O C. p-value = 2*NORM.S.DIST(-1.01,1) = 0.3125 O D. p-value = NORM.S.DIST(-1.01,1) = 0.1562 b. What is the statistical decision? O A. Since the p-value is less than a = 0.10, reject Ho . B. Since the p-value is less than a = 0.10 , do not reject Ho O C. Since the p-value is greater than a = 0.10 , do not reject Ho . O D. Since the p-value is greater than a = 0.10, reject Ho
