Question: A hotel manager looks to enhance the initial impressions that hotel guests have when they check in. Contributing to initial impressions is the time it takes to deliver a guest's luggage to the room after check-in. A random sample of 20 deliveries on a particular day were selected in Wing A of the hotel, and a random sample of 20 deliveries were selected in Wing B. The results are stored in Luggage.xls Analyze the data and determine whether there is a difference in the mean delivery time in the two wings of the hotel. (Use a = 0.05.)

Please report the name of the test(s), the test-statistic and critical value of the test(s) you used, your reasoning behind selecting that test(s), and your final conclusions.
