Question:

A major North American city has four competing newspapers: the Globe and Mail

(G&M), Post, Star and Sun. To help design advertising campaigns, the advertising managers of the newspapers need to know which segments of the newspaper market are reading their papers. A survey was conducted to analyze the relationship between newspapers read and occupation. A sample of newspaper readers was asked to report which newspaper they read—Globe and Mail (1), Post (2), Star (3), Sun (4)—and indicate whether they were blue-collar workers (1), white-collar workers (2), or professionals

(3). Some of the data are listed here.
