No. 3: Recently airlines have cut services, such as meals and snacks during flights, and started chargingextra for some services, such as accommodating overweight luggage, last-minute flight changes, and petstraveling in the cabin. However, they are still concerned about service. Recently, a group of four carriers hiredBrunner Marketing Research Inc. to survey passengers regarding their level of satisfaction with a recent flight.The survey included questions on ticketing, boarding, in-flight service, baggage handling, pilot communication,and so forth. Twenty-five questions offered a range of possible answers: excellent, good, fair, or poor. Aresponse of excellent was given a score of 4, good a 3, fair a 2, and poor a 1. These responses were then totaled,so the total score was an indication of the satisfaction with the flight. The greater the score, the higher the levelof satisfaction with the service. The highest possible score was 100. Brunner randomly selected and surveyedpassengers from the four airlines. Below is the sample information. Is there a difference in the mean satisfactionlevel among the four airlines? Use the .01 significance level.NorthernWTAРосonoBranson94757068906873708577767280837865888074686565
