This is a modification of Exercise 1.4. The risk of getting lung cancer at some point in one's life for men who have never smoked is about 13 in 1000. The risk for men who smoke is just over 13 times the risk for nonsmokers (Source: Villeneeve and Lau, 1994).
a. Expressed as a percentage, what is the lifetime risk of lung cancer in men who never smoked?
b. What is the approximate lifetime risk of getting lung cancer for men who smoke?
c. In the introduction to this exercise it was stated that "The risk for men who smoke is just over 13 times the risk for non-smokers." Using the terminology of this chapter, what name applies to the statistic in that statement (e.g., odds, risk, relative risk)?
