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. minutes. You select a random sample of 81 orders. The sample mean waiting time is 3.87 minutes, with a sample standard deviation of 0.9 minute. Complete parts (a) and (b) below. a. At the 0.05 level of significance, there evidence that the population mean waiting time i different from 3.7 minutes? State the null and alternative hypotheses. 3.7 3.7 Hot H₁: (Type integers or decimals.) Determine the test statistic. The test statistic is 1.7. (Round to two decimal places as needed.) Find the p-value. p-value = (Round t three decimal places s needed.)
