uestion He You are the manager of a restaurant for a fast-food franchise. Last month, the mean wating 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 64 orders. The sample mean wating me a 3.48 minutes, with a sample standard deviation of 0.8 minute. Complete parts (a) and (b) below (Type integers or decimals) Determine the test statistic The test statistic is -2.20 (Round to two decimal places as needed) Find the p-value p-value 0.001 (Round to three decimal places as needed) State the conclusion Reject H. There is sufficient evidence to conclude that the population mean waiting time is different from 37 b. Because the sample size is 64, do you need to be concerned about the shape of the population distribution when conducting the test in (a? Explain. Choose the comect awer below OA. Yes, because n is equal to 64, the sampling distribution of the 1 lest cannot be determined in general, the 1 test requires a larger sample size OB Yes, because n is equal to 64, the sampling distribution of the t test cannot be determined in general, the 1 test is only appropriate for a normally distributed sample OC. No, because n is equal to 64, the sampling distribution of the 1 test is approximately normal. In general, the 1 test is appropriate for this sample sine unless the population is skewed OD. No, because n is equal to 64, the sampling distribution of the 1 test is approximately normal, in general, the 1 test is appropriate for a large sample size
