Chapter 2.1, Problem 7E

The Canmark Research Center Airport Customer Satisfaction Survey uses an onlinequestionnaire to provide airlines and airports with customer satisfaction ratings for all aspects of the customers' flight experience (airport survey 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 (E), Very Good (V), Good (G), Fair (F), and Poor (P), 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.

a. Use a percent frequency distribution and a bar chart to summarize these data. What do these summaries indicate about the overall customer satisfaction with the Delta flight?
b. The online survey questionnaire enabled respondents to explain any aspect of the flight that failed to meet expectations. Would this be helpful information to a manager looking for ways to improve overall customer satisfaction on Delta flights? Explain.
