14.10: A supervisor in the Department of Rehabilitative Services is critical of the performance of one of her counselors. The counselor is expected to arrange job training for those in need of vocational rehabilitation so that they may find employment. Yet the counselor has managed to place just 35% of his clients. The counselor argues that he is actually doing a good job and that the reason for his overall low rate of placement is that most of his clients are severely disabled, which makes them very difficult to place. The counselor's case load is presented in the accompanying table. Percentage the table appropriately and evaluate who is correct- the superviso or the counselor.
                                                Not Severely          Severely
Job Placement                           Disabled             Disabled
