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.) USE SALT (a) Assuming that the duration of smoking is normally distributed, what proportion of men in this age group have smoked for more than 21 years?
