Question
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 3.6 minutes. You select a random sample of 64 orders. The sample mean waiting time is 3.34 minutes, with a sample standard deviation of 0.8 minute. At the 0.10 level of significance, is there evidence that the population mean waiting time is different from 3.6 minutes? State the null and alternative hypotheses. Ho HY H₁ H (Type integers or decimals.) Determine the test statistic. The test statistic is (Round to two decimal places as needed.) State the conclusion. Ho- There is evidence to conclude that the population mean waiting time is different from 3.6 minutes.
