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 5 116 20 15 8 17 4 10 2 9 14 13 3 19 6 11 12 18 7 Use α = 0.05 and test whether there is a significant difference among the quality of training provided by the four programs.
