Assignment Help:

A psychologist developed a test designed to help predict whether production-line workers in a large industry will perform satisfactorily. A test was administered to all new employees in a corporation. At the end of the first year of work, these employees were rated by their supervisors: 18% were rated excellent, 53% were rated satisfactory and 29% were rated poor. 48% percent of those rated excellent passed the psychologist's test, as did 22% of those rated satisfactory and 12% of those rated poor.
