Question
Delta Airlines quotes a flight time of 2 hours, 5 minutes for its flights from Cincinnati to Tampa. Suppose we believe that actual flight times are uniformly distributed between 2 hours and 2 hours, 20 minutes.
What is the probability that the flight will be no more than 5 minutes late (to 2 decimals)?
What is the probability that the flight will be more than 10 minutes late (to 2 decimals)?
What is the expected flight time, in minutes?
What is the standard deviation for the flight time, in minutes? (to 3 decimals)
