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 37 months
and a standard deviation of 5 months. Using the empirical rule (as
presented in the book), what is the approximate percentage of cars
that remain in service between 42 and 47 months?
