Cardiovascular Disease, Pulmonary Disease The duration of cigarette smoking has been linked to many diseases, including lung cancer and various forms of heart disease. Suppose we know that among men ages 30-34 who have ever smoked, the mean number of years they smoked is 12.7 with a standard deviation of 5.2 years. For women in this age group, the mean number of years they smoked is 9.4 with a standard deviation of 3.1. (Assume that number of years spent smoking can be measured exactly and no continuity correction is necessary. Round your answers to four decimal places.)
