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 ABCD 5 2 18 17 14 10 16 7 3 9 15 13 1 20 6 11 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 H: Median Median Median Median Median Median Median Ho: Median H₂: Median Median Median ⒸH: Median - Median H₁: Median > Median Median Median Median Median 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. ⒸH: There is no difference in the quality of the training for the programs. H: 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 xX State your conclusion.
