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 ABCD 5 14 10 16 4 7 2 18 17 13 3 9 15 1 11 12 20 6 12 19 8 Use a = 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. Ho: Median Median Median Median A H₂: Median = Median Median Median А Ho: Median = Median = Median Median Median Median = = Median Median ⒸH: Median = Median Median Median A H₂: Median > Median < Median > Median H: There is a difference in the quality of the training for the programs. H₂: There is no difference in the quality of the training for the programs. a ⒸH₁: There is no difference in the quality of the training for the programs. H₂: 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.) 4.29 x Find the p-value. (Round your answer to three decimal places.) p-value = 0.021 X State your conclusion
