In determining automobile mileage ratings, it was found that the mpg (X) for a certain model is normally distributed, with a mean of 35 mp a. Find P(X < 34). P(X< 34) =O (Round to four decimal places as needed.) b. Find P(32 37). P(X> 37) =O (Round to four decimal places as needed.) d. Find P(X> 34). P(X> 34) =O (Round to four decimal places as needed.) e. Find the mileage rating that the upper 11% of cars achieve. The mileage rating that the upper 11% of cars achieve is mpg. (Round to two decimal places as needed.)
