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 concermed about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data? E Click the icon to view the data table. O B. Ho: The amount of smoking is independent of seat belt use. H: The amount of smoking is not independent of seat belt use. OC. Ho: Heavy smokers are not less likely than non-smokers to wear a seat belt. H: Heavy smokers are less likely than non-smokers to wear a seat belt. O D. Ho: Heavy smokers are less likely than non-smokers to wear a seat belt. H: Heavy smokers are not less likely than non-smokers to wear a seat beit. Determine the test statistic. (Round to three decimal places as needed.) Determine the P-value of the test statistic. P.Value = (Round three decimal places as needed.) 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 Use a 0.05 significance level to test the claim that the amount of smoking belts. Is this theory supported by the sample data? O A. There is not sufficient evidence to reject the claim that the amount of smoking is independent of seat belt use. The theory is not supported by the sample data. O B. There is sufficient evidence to reject the claim that the amount of smoking is independent of seat belt use. The theory is not supported by the sample data. OC. There is not sufficient evidence to reject the claim that heavy smokers are less likely than non-smokers to wear a seat belt. The theory is supported by the sample data. O D. There is sufficient evidence to reject the claim that heavy smokers are less likely than non-smokers to wear a seat belt.
