A manager is interested in determining if the population standard deviation has dropped below 136. Based on a sample of n = 27 items selected randomly from the population, conduct the appropriate hypothesis test at a 0.10 significance level. The sample standard deviation is 111. Determine the null and alternative hypotheses. Α. Ho: 02 > 18,496 HA: 02 <18,496 O B. Ho: 62 = 136 HA: 02 # 136 OC. Ho sº < 18,496 HA: 02 >18,496 OD. Ho: 62 <136 HA: 02 > 136 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.) A. If the test statistic, x? >xa = reject Ho. Otherwise, do not reject Ho. B. If the test statistic, x2 >xa/2 , reject Ho or if the test statistic, x2 <x1-2/2 =, reject Ho. Otherwise, do not reject Ho- OC. If the test statistic, x2 < x?-« reject Ho. Otherwise, do not reject Ho-
