The article “High Cumulative Risk of Lung Cancer Death among Smokers and Nonsmokers” (P. Brennan, et al. American Journal of Epidemiology, 2006:1233–1241) states that the probability is 0.24 that a man who is a heavy smoker will contract lung cancer. True or false: a) In a sample of 100 men who are heavy smokers, exactly 24 of them will contract lung cancer. b) In a sample of 100 men who are heavy smokers, the number who will contract lung cancer is likely to be close to 24, but not exactly equal to 24. c) As more and more heavy-smoking men are sampled, the proportion who contract lung cancer will approach 0.24.
