What is the probability that for 36 jets on a given runway, total taxi time will be less than 320 minutes? (Round your answer to four decimal places) b. What is the probability that for 36 jets on a given runway, total taxi and takeoff will be more than 275 minutes? ( round youre answer to four decimal places) c. What is the probability that for 36 jets on a given runway, total taxi and takeoff time will be between 275 and 320? (Round your answer to four decimal places)
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 3.2 minutes. Assume that the distribution of taxi and takeoff time is approximately normal. You may assume that the jets are lined up on a runway so that no one taxies and takes off immediately after the other, and they take off one at a time on a given runway.
