A study of the effects of smoking and the risk of developing an abdominal aortic aneurysm (AAA) analyzed 210 men with AAA and 200 men without AAA. The study revealed an odds ratio of 3.0 associated with smoking, with 95% confidence intervals from 1.2 to 6.4.The effect of the level of exposure did not seem to determine the risk of AAA in patients older than aged 50 years. What is the most appropriate conclusion to draw from this study? A. A male who smokes has a 3 times greater likelihood of developing an AAA than a male who does not smoke B. The study has a p value greater than 0.05 C. If a 90% confidence interval was used, the results would probably include 1.0 D. Use of a larger sample would increase the confidence interval
