Many airlines use surveys to collect data on customer satisfaction related to flight experiences. 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.
