A large corporation sends many of its first-level managers to an off-site supervisory skills training course. Four differentmanagement development centers offer this course. The director of human resources would like to know whether there is adifference among the quality of training provided at the four centers. An independent random sample of five employees was chosenfrom each training center. The employees were then ranked 1 to 20 in terms of supervisory skills.
