A manager is interested in determining if the population standard deviation has dropped below 124. Based on a sample of n = 26 items selected randomly from the population, conduct the appropriate hypothesis test at a 0.05 significance level. The sample standard deviation is 124. Determine the null and alternative hypotheses. O A. Ho: 02 <15,376 HA: 02 > 15,376 *B. Ho: 02 215,376 HA: 02 <15,376 OC. Ho G2 = 124 HA: 02 #124 XD. Ho: 02 < 124 HA: 02 > 124 State the decision rule. Select the correct choice below and, if necessary, fill in any answer boxes to complete your choice. (Round to four decimal places as needed.) O A. If the test statistic, x2 >x212 = reject Ho or if the test statistic, x2 < x7-9/2=, reject Ho. Otherwise, do not reject Ho O B. If the test statistic, x?>xa = reject Ho. Otherwise, do not reject Ho OC. If the test statistic, x2 <x*-a = reject Ho. Otherwise, do not reject Ho
