1. A company has a policy of retiring company cars; this policy looks at number of miles driven, purpose of trips, style of car and other features. The distribution of the number of months in service for the fleet of cars is bell-shaped and has a mean of 46 months and a standard deviation of 9 months. Using the 68-95- 99.7 (Empirical) Rule, what is the approximate percentage of cars that remain in service between 55 and 73 months? The approximate percentage of cars that remain in service between 55 and 73 months is %. Do not enter the percent symbol.)
