Question
A manager is interested in determining if the population standard deviation has dropped below 103. 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 69. O D. Họ: o = 103 HA:o # 103 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, x>x212 =, reject H, or if the test statistic, x <x% -g12=, reject Ho. Otherwise, do not reject H,. %3D B. If the test statistic, x >x = reject Ho. Otherwise, do not reject Ho- OC. If the test statistic, x <x- reject Ho. Otherwise, do not reject . Find the test statistic, x. (Round to two decimal places as needed.) Choose the correct conclusion below. O A. Reject Ho. There is insufficient evidence that the population standard deviation is less than 103. O B. Do not reject Ho. There is insufficient evidence that the population standard deviation is less than 103. O C. Do not reject Ho. There is sufficient evidence that the population standard deviation is less than 103. O D. Reject Ho. There is sufficient evidence that the population standard deviation is less than 103.
