Job satisfaction of professionals was examined in the article “Psychology of the Scientist: Work-Related Attitudes of U.S. Scientists” (Psychological Reports [1991]: 443–450). Each person in a random sample of 778 teachers was classified according to a job satisfaction variable and also by teaching level, resulting in the accompanying two-way table. Can we conclude that there is an association between job satisfaction and teaching level? Test the relevant hypotheses using α = .05.
