The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.4 minutes and a standard deviation of 3 minutes. Assume that the distribution of taxi and takeoff times is approximately normal. You may assume that the jets are lined up on a runway so that one taxies and takes off immediately after the other, and that they take off one at a time on a given runway.

(a) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (Use 3 decimal places.)

Incorrect: Your answer is incorrect.

(b) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (Use 3 decimal places.)

(c) What is the probability that for 35 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes? (Use 3 decimal places.)
