Suppose that the lowa Express is a super-speedy train that makes daily trips (one trip per day) around the full perimeter of lowa's border. Assume the travel time of a given trip is a random variable that is normally distributed with a mean of 5 hours and a standard deviation of 30 minutes. Further assume that from one day to the next, trip times are independent of each other.
