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. A response 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 level of satisfaction with the service. The highest possible score was 100. Brunner randomly selected and surveyed passengers from the four airlines. Below is the sample information. Is there a difference in the mean satisfaction level among the four airlines? Use the .01 significance level.

- Which of these are categorical and which are quantitative?arrow_forwardAccording to the American Psychological Association, married adults tend to be happier than single adults. A researcher wanted to determine how much happier married adults are. The researcher asked eighteen married adults and seventeen single adults how happy they are on a scale from 1 to 10, with 1 being very unhappy and 10 being very happy. The results of the survey are shown below. Married: 3, 9, 10, 10, 7, 7, 9, 8, 6, 6, 5, 5, 7, 10, 7, 6, 7, 10 Single: 5, 5, 3, 2, 8, 2, 7, 2, 1, 6, 4, 4, 1, 2, 3, 2, 10 Assume both follow a Normal distribution.
