Problem 6 The average travel time (one way) from National University to Robinsons Magnolia is 25 minutes according to a survey conducted by NU engineering students. If we assume that commuting times are normally distributed and that the standard deviation is 6.1 minutes, what is the probability that a randomly selected commuter spends more than 30 minutes from NU to Robinsons Magnolia? Less than 18 minutes?
