The taxi and take off time for commercial jet is a random variable x with a mean of 8.2 minutes and standard deviation of 3 minutes. Assume that the distribution of taxi and take off time 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. A) What is the probability for 37 jets on a given runway, total taxi and take off time will be less than 320 minutes? (Round your answer to four decimal places) B) what is the probability that for 37 jets on a given runway, total taxi take off time is 275 minutes? (Round your answer to four decimal places) C) what is the probability that for 37 jets on a given runway, total taxi and take off time will be between 275 and 320 minutes? Round your answer to four decimal places)
