In determining automobile mileage ratings, it was found that the mpg (X) for a certain model is normally distributed, with a mean of 34 mpg and a standard deviation of 1.1 mpg. Complete parts a through e below.
a. Find P(X <33).
P(X< 33) = 0. 1817 (Round to four decimal places as needed.)
b. Find P(32 <x < 38).
P(32 <x< 30) = (Round to four decimal places as needed.)
