The accompanying two-way table was constructed using data in the article "Television Viewing and Physical Fitness in Adults" (Research Quarterly for Exercise and Sport, 1990: 315-320). The author hoped to determine whether time spent watching television is associated with cardiovascular fitness. Subjects were asked about their television-viewing habits and were classified as physically fit if they scored in the excellent or very good category on a step test. We include Minitab output from a chi-squared analysis. The four TV groups corresponded to different amounts of time per day spent watching TV (0, 1-2, 3-4, or 5 or more hours). The 168 individuals represented in the first column were those judged physically fit. Expected counts appear below observed counts, and Minitab displays the contribution to x₂ from each cell. State and test the appropriate hypotheses using α = .05.
