(with staff ng f xed at the original levels), the airline noticed that a lot of the people who opt for the manual check-in really don’t need the extra services there and could have used the automated check-in. Instead of the original 35% and 50% that go to manual and automated, respectively, suppose that through more effective “encouragement” from people with red blazers and loud voices, it could be made 10% and 75% instead. (There probably are 10% of passengers who genuinely need the extra services of manual check-in.) How would this shift in passenger attitudes (or maybe bravery) affect average total time in system of passengers? Base your comparison on 200 replications of the model in each conf guration.
