A bank with a management training program is considering promotion of one of two trainees in the Metro West division. The bank has asked for feedback for each of the trainees (that is, feedback from managers and peers). The overall ratings for each trainee are shown in Exhibit 10.16 below. The ratings range from 1to 6, where 1 corresponds to the best performance, and 6 corresponds to the worst performance. At the 2.5% level of significance, is there evidence of a difference in the performance ratings of the two trainees? Based on these performance ratings, which trainee should be promoted?
