You may need to use the appropriate technology to answer this question. A large corporation sends many of its first-level managers to an off-site supervisory skills training course. Four different management development centers offer this course. The director of human resources would like to know whether there is a difference among the quality of training provided at the four centers. An independent random sample of five employees was chosen from each training center. The employees were then ranked 1 to 20 in terms of supervisory skills. A rank of 1 was assigned to the employee with the best supervisory skills. Suppose the ranks are as shown. Course A B C D 2 1 16 17 15 8 18 5 7 3 10 12 13 4 19 6 11 14 20 9 Use = 0.05 and test whether there is a significant difference among the quality of training provided by the four programs. State the null and alternative hypotheses. H0: MedianA = MedianB = MedianC = MedianD Ha: MedianA > MedianB < MedianC > MedianD H0: MedianA = MedianB = MedianC = MedianD Ha: MedianA MedianB MedianC MedianD H0: MedianA MedianB MedianC MedianD Ha: MedianA = MedianB = MedianC = MedianD H0: There is a difference in the quality of the training for the programs. Ha: There is no difference in the quality of the training for the programs. H0: There is no difference in the quality of the training for the programs. Ha: There is a difference in the quality of the training for the programs. Find the value of the test statistic. (Round your answer to two decimal places.) Find the p-value. (Round your answer to three decimal places.) p-value = State your conclusion. Do not reject H0. There is not sufficient evidence to conclude that there is a significant difference among the quality of training provided by the four programs. Reject H0. There is sufficient evidence to conclude that there is a significant difference among the quality of training provided by the four programs. Reject H0. There is not sufficient evidence to conclude that there is a significant difference among the quality of training provided by the four programs. Do not reject H0. There is sufficient evidence to conclude that there is
