Discussion Questions:
1. After returning from the training session at Hamburger University, a McDonald’s store owner selected a random sample of 362 drive-thru customers and carefully measured the time it took from when a customer entered the McDonald’s property until the customer had received the order at the drive-thru window. These data are in the file called McDonald’s Drive-Thru Waiting Times. Note, the owner selected some customers during the breakfast period, others during lunch, and others during dinner. Test, using an alpha level equal to 0.05, to determine whether the mean drive-thru time is equal during the three dining periods (breakfast, lunch, and dinner.)
2. Referring to question 1, write a short report discussing the results of the test conducted. Make sure to include a discussion of any ramifications the results of this test might have regarding the efforts the manager will need to take to reduce drive-thru times.
When you’re on the go and looking for a quick meal, where do you go? If you’re like millions of people every day, you make a stop at McDonald’s. Known as “quick service restaurants” in the industry (not “fast food”), companies such as McDonald’s invest heavily to determine the most efficient and effective ways to provide fast, high-quality service in all phases of their business.
