The owners of a fast-food franchise, looking to reduce wait times for customers, launched a plot prog could use a smartphone app to place orders. The accompanying data set shows the mean wait times (in seconds) for in- store and drive-through customers at 30 restaurants participating in the pilot program and at 30 restaurants not participating in the program. Assume that the population standard deviation of mean wait times is 30 seconds for both groups of restaurants and that the mean wait times are normally distributed for both groups of restaurants. Let the mean wait times at the restaurants not in the program be the first sample, and let the mean wait times at the stores in the program be the second sample. At the 0.05 level of significance, is there evidence that the smartphone app reduces wait times? Perform the test using Excel. Find the test statistic, rounded to two decimal places, and the p-value, rounded to thre decimal places.
