Problem 2. (1 point) There are four student employees at the Computer Help Desk. The supervisor wants to determine it there is a ditterence in the mean number ot clients served per nour between the four employees. The data from a random selection of hours is depicted below. The second table displays results trom an ANOVA test on this data with som.ware. The supervisor claims there is a difference. in the mean number of clients served per hour for these employees. Alan aeth Carl Denise Part a) Which of the following hypotheses could reasonably be tested by the data presented in the study? C) A. It the data are placed into tour groups determined by the employee as above, the medians of the number ot clients served are equal. o B. There is no correlation between employee and the number ot clients served. Clients Served in the Hour 4 5 4 4 4 6 3 o 3 5 5 3 7 4 4 3 2 4 2 Remaining time: 181:10 (min:sec) 27.5 85.5 43.5 33.5 C) C. In the population ot clients calling the computer help desk, if placed into tour groups determined by their helping employee as above, the variances of the number ot clients served are equal. O O . In the tour groups ot clients determined by their employee helper, the sample means ot the number ot clients are equal. E. In the tour groups of clients determined by their employee helper, the sample variances ot the number of clients are equal part b) For the test outlined above and at a level of significance ot 5%, provide the critical value you would use Part c) Under the null hypothesis, the statistic should be an observation trom which probability distribution? o A. The Chi-squared distribution on tour degrees of freedom. o B. The t distribution on two degrees ot freedom. o C. The Chi-squared distribution on three degrees ot treedom. o D. The standard Normal distribution. O E. The Chi-squared distribution on two degrees ot treedom. The F3J0 distributiom o F. part d) It the test statistic was found to be equal to 728092105263158, would you reject or not reject your null hypothesis at the 5% significance level? o A. Not reject o B.
