Please Help ASAP.
Lee Roy Selmon's Restaurant chain has decided to put on probation any location that is not maintaining their standard wait time of 20 minutes. The Warner Robins location has been observed on 204 orders, whose sample average (mean) wait time was 21.2 minutes, with standard deviation of 6.83 minutes. Is there evidence, at a = 0.10 that their true mean wait time is greater than 20 minutes.
a. Find the Null and Alternative Hypotheses
b. Compute the p-value. Round to 3 decimal places.
c. What can you conclude? (Options Below)
A. Because the p-value is less than .1, we have sufficient evidence that the true mean wait time is greater than 20 minutes.
B. Because the sample mean exceeds 20 minutes by more than 0.1 minutes, we have sufficient evidence that the mean wait time is greater than 20 minutes.
C. Because the p-value is greater than .1, we do not have sufficient evidence that the true mean wait time is greater than 20 minutes.
D. Because the sample mean does not exceeds 20 minutes by more than 0.1*sample size minutes, we do not have sufficient evidence that the mean wait time is greater than 20 minutes.
E. Because the p-value is greater than .1, we have sufficient evidence that the true mean wait time is greater than 20 minutes.
F. Because the p-value is less than .1, we do not have sufficient evidence that the true mean wait time is greater than 20 minutes.
