Question 2: Alabama Airlines provides commuter service. As a product of airline deregulation, Alabama Air joined the growing number of short-haul, point-to-point airlines, including Lone Star, Comair, Atlantic Southeast, and Skywest. Alabama Air was started and managed by two former pilots, David Douglas and Michael Hanna. One of Alabama Air's top competitive priorities is on-time arrivals. The airline defines "on-time" to mean any arrival that is within 20 minutes of the scheduled time. Mike Hanna decided to personally monitor Alabama Air's performance. Each week for the past 30 weeks, Hanna checked a random sample of 100 flight arrivals for on-time performance. The table that follows contains the number of flights that did not meet Alabama Air's definition of on time: Late Flights Sample (Week) Late Flights 2 Sample (Week) 16 2 2 4 17 3 3 10 18 7 4 4 19 3 5 I 20 2 6 1 21 7 13 22 8 9 23 9 11 24 10 0 25 11 3 26 3743221 12 4 27 0 13 2 28 1 14 2 29 3 15 8 30 4 a. In this case, which quality control chart(s) will be appropriate? b. Construct the control chart(s) you have chosen in part (a). c. For the next five weeks, Mike continues to sample the flights and observes that the number of late flights are 11, 9, 4, 12, and 8, respectively. What can Mike Hanna report about the quality of service: Is the process in control?
