The Chapter Problem uses measured service times in Data Set 25 “Fast Food” in Appendix B. Go to one or more fast food restaurants and collect your own service times. Compare the results to those found in Data Set 25 in Appendix B.

Data Set 25: Fast Food 

Data are from 400 observations (first five rows shown here) of drivethru service times (sec) at different fast-food restaurants. Times begin when a vehicle stops at the order window and end when the vehicle leaves the pickup window. Lunch times were measured between 11:00 AM and 2:00 PM, and dinner times were measured between 4:00 PM and 7:00 PM. Data collected by the author.
