customer satisfaction ratings for all aspects of the customers’ flight experience (airportsurvey website, July 2012). After completing a
flight, customers receive an e-mail asking them to go to the website and rate a variety of factors, including the reservation process,
the check-in process, luggage policy, cleanliness of gate area, service by flight attendants, food/beverage selection, on-time arrival,
and so on. A five-point scale, with Excellent, Very Good, Good, Fair, and Poor, is used to record customer ratings. Assume
that passengers on a delta Airlines flight from Myrtle beach, South Carolina, to Atlanta, Georgia, provided the following ratings for the
question, “Please rate the airline based on your overall experience with this flight.” The sample ratings are shown below.
