Be sure to include the entire Hypotheis Test process in your written work. There are four student employees at the Computer Help Desk. The supervisor wants to determine if there is a difference in the mean number of clients served per hour between the four employees. The data from a random selection of hours is depicted below. The supervisor claims there is a difference in the mean number of clients served per hour for these employees.

O A. In the four groups of clients determined by their employee helper, the sample means of the number of clients are equal. O B. If the data are placed into four groups determined by the employee as above, the medians of the number of clients served are equal. O C. There is no correlation between employee and the number of clients served. O D. In the population of clients calling the computer help desk, if placed into four groups determined by their helping employee as above, the variances of the number of clients served are equal. O E. In the four groups of clients determined by their employee helper, the sample variances of the number of clients are equal.Part D) For the test outlined above and at a level of signicance of2.5%, provide the critical value you would use.
