A Civil engineer commutes daily from his suburban home to his midtown office. The average time for a one-way trip is 25 minutes, with a standard deviation of 4.2 minutes. Assume the distribution of trip times to be normally distributed. a) What is the probability that a trip will take at least 35 minutes? (0.5 points) b) If the office opens at 9:00 A. M. and the engineer leaves his house at 8:40 A. M. daily, what percentage of the time is he late for work? (0.5 points) c) If he leaves the house at 8:32 A. M. and coffee is served at the office from 8:50 A. M. until 9:00 A. M., what is the probability that
