for its employees, depending on the success or failure of a pilot program. Ten employees were randomly selected and given a questionnaire designed to measure their attitude toward their job. Each was then permitted to design and follow a flextime workday. After six months, attitudes toward their job were again measured. The resulting attitude scores are display in the table below. 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 flextime program. Test using α = .05.

5. Suppose you want to use the Kruskal-Wallis H-test to compare the probability distributions of three populations. The following are independent random samples selected from the three populations: I: 66, 23, 55, 88, 58, 62, 79, 49 II: 19, 31, 16, 29, 30, 33, 40 III: 75, 96, 102, 75, 98, 78 a. What type of experimental design was used? b. Specify the null and alternative hypotheses you would test. c. Specify the rejection region you would use for your hypothesis test at α = .01. d. Conduct the test at α = .01. 6. Compute Spearman’s rank correlation coefficient for each of the following pairs of sample observations:

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
