Organizational analyst Ann T. Gravity is examining the Peter Principle, which contends that people will rise in an organization until they reach their level of incompetence. She feels that this means that proportionately more competent people will be found at the lower level of the organization. To test this question, she decides to ask students to rate assistant professors, associate professors, and full professors. Based on these ratings, she classified the competence of professors as high, medium, or low. Interpret the accompanying table; calculate any necessary statistics. Refer to the book€™s website for the calculation of gamma in larger tables.
