Fuel economy estimates for automobiles built one year predicted a mean of 26.2 mpg and a standard deviation of 5.8 mpg for highway driving. Assume that a Normal model can be applied. Use the 68-95-99.7 Rule to complete parts a) through e). Using the 68-95-99.7 rule, the central 99.7% of autos can be expected to be found in the interval from (Do not round. Type integers or decimals.) c) About what percent of autos should get more than 32 mpg? Using the 68-95-99.7 rule, about % of autos should get more than 32 mpg. (Do not round. Type an integer or a decimal.) d) About what percent of autos should get between 32 and 37.8 mpg? Using the 68-95-99.7 rule, about % of autos should get between 32 and 37.8 mpg. (Do not round. Type an integer or a decimal.) e) Describe the gas mileage of the best 2.5% of cars. Choose the correct answer below. A. They get more than 32 mpg. B. They get more than 43.6 mpg. C.
