The taxi and takeoff time for commercial jets is a random variable x with a mean of 8.3 minutes and a standard deviation of 3.3 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 37 jets on a given runway, total taxi and takeoff time will be less than 320 minutes? (round your answer to four decimal ) what is the probability that for 37 jets on a given runway, total taxi and takeoff time will be more than 275 minutes? (round your answer to four decimal ) what is the probability that for 37 jets on a given runway, total taxi and takeoff time will be between 275 and 320 minutes? (round your answer to four decimal places.)
