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.

Use α = 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
H: Median = Median = Median = Median D
Ho: 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.
Ho: 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.
Ho: Median
H: Median
Median = Median = Median D
Median # Median c + Median D
Ho: Median = Median = Median = Median
H: Median > Median Median > Mediano
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 =
