You are the manager of a restaurant for a fast-food franchise. Last month, the mean waiting time at the drive-through window for branches in your geographical region, as measured from the time a customer places an order until the time the customer receives the order, was 3.7 minutes. You select a random sample of 81 orders. The sample mean waiting time is 3.59 minutes, with a sample standard deviation of 0.9 minute. Complete parts (a) and (b) below. Question content area bottom Part 1 a. At the 0.10 level of significance, is there evidence that the population mean waiting time is different from 3.7 minutes?
