The time to fly between New York City and Chicago is uniformly distributed with a minimum of 120 minutes and a maximum of 150 minutes. Respond to the following questions: What is the probability that a flight takes time less than 135 minutes? * a-P(X<135)=0 b-P(x<135) = 0.5 c-P(X<135)=0.135 d-P(X<135)=0.15 The mean flying time and the standard deviation are: * a-Mean=135; Standard-deviation=8.66 minutes. b-Mean=135; Standard-deviation=75 minutes. c-Mean=8.66; Standard-deviation=75 minutes d-Mean=8.66; Standard-deviation=135 minutes What is the probability that a flight takes...
