Recent Environmental Protection Agency (EPA) fuel economy estimates for automobile models tested predicted a mean of 24.8 mpg and a standard deviation of 6.2 mpg for highway driving. Assume the data is normally distributed. Between which two mpg would you expect 68% of all cars to fall? Between 12.4 mpg and 37.2 mpg Between 18.6 mpg to infinity Between 18.6 mpg and 31 mpg Between 12.4 mpg and 18.6 mpg
