A study of seat belt users and nonusers yielded the randomly
selected sample data summarized in the accompanying table. Use a
0.05 significance level to test the claim that the amount of
smoking is independent of seat belt use. A plausible theory is that
people who smoke are less concerned about their health and safety
and are therefore less inclined to wear seat belts. Is this theory
supported by the sample data?
