You are the manager of a restaurant for a fast-food franchise. Last month, the mean waiting time at the counter, as measured from the time a customer places an order until the time the customer receives the order, was 3.7 minutes. The franchise helped you to institute a new process intended to reduce waiting time. You select a random sample of 64 orders. The sample mean waiting time is 3.56 minutes, with a sample standard deviation of 0.8 minutes. At the 0.01 level of significance, is there evidence that the population mean waiting time is now less than 3.7 minutes? Click here to view page 1 of the table of the critical values of t. Click here to view page 2 of the table of the critical values of t. State the null and alternative hypotheses. O A. Ho: Hs3.56 OB. Ho: Hs3.7 H:u>3.56 H:u>3.7 OD. Ho: H=3.7 H;:u#3.7 OC.
