Attitudes toward top corporate managers. Scandals involving large U.S. corporations (e.g., Enron, WorldCom, and Adelphia) have had a major impact on the public’s attitude toward business managers. In a Harris Poll administered immediately after the Enron scandal, a national sample of 2,023 adults were asked to agree or disagree with the following statement: “Top company managers have become rich at the expense of ordinary workers” (The Harris Poll, #55, Oct. 18, 2002). The response categories (and number of respondents in each) were strongly agree (1,173), somewhat agree (587), somewhat disagree (182), and strongly disagree (81). Suppose that prior to the Enron scandal, the percentages of all U.S. adults falling into the four response categories were 45%, 35%, 15%, and 5%, respectively. Is there evidence to infer that the percentages of all U.S. adults falling into the four response categories changed after the Enron scandal? Test using  = .01.
