Transcribed Image Text: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,.

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.
