Problem 7. In a study of the association between cigarette smoking and lung cancer, 1,357 male lung cancer patients were compared with 1,357 controls in terms of their cigarette consumption as follows: Cigarette Consumption Daily 0 1-5- 15- 25- 50- Total Lung cancer patients 7 49 516 445 299 41 1,357 Controls 61 91 615 408 162 20 1,357 Compute the odds ratio and log odds ratio in each of the 5 smoking groups compared with non- smokers. Find confidence intervals and graphically display. Comment and interpret. Can relative risks be estimated. Why or why not.
