11) A flextime program permits employees to design their own workweek to meet their personal needs. A firm starts a pilot flextime program to test its results. Nine random employees were given a questionnaire to measure their attitude toward their job before and after using a flextime program. The resulting attitude scores are displayed in the accompanying table. The higher the​ score, the more favorable the​ employee's attitude toward his or her work. Use a nonparametric test procedure to evaluate the success of the pilot program. Test using α=0.05.
