You are the manager of a restaurant for a fast-food franchise. Last month, the mean waiting time at the drive-through window, 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 institute a new process intended to reduce waiting time. You select a random sample of 64 orders. The sample mean waiting time is 3.57 minutes, with a sample standard deviation of 0.8 minute. At the 5% level of significance, is there evidence that the population mean waiting time is now different from 3.7 minutes? What if you choose 1% level of significance?
