1) 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...

A professor commutes daily from her suburban home to her campus office. The average time for a one-way trip is 20 minutes, with a standard deviation of 5 minutes. Assume the distribution of trip times to be normally distributed. If she leaves the house at 9:00 am and coffee is served at the office from 9:10 am until 9:20 am, what is the probability that she arrives to the office after coffee has finished being served?
Dave drives to work each morning at about the same time. His commute time is normally distributed with a mean of 38 minutes and a standard deviation of 5 minutes. The percentage of time that his commute time exceeds 44 minutes is equal to the area under the standard normal curve that lies to the ___ of ___.
David can take on three possible routes from his home to his office in the morning. The percentage of days on routes A, B, and C to his office were 45%, 30%, and 25%, respectively. The traveling time on each of these routes is normally distributed with mean and standard deviation given in the following table: Route A Route B RouteC Mean 30 mins 35 mins 28 mins Standard Deviation 10 mins 8 mins 12 mins David left his home...
Can someone explain all these questions? B5. In order to go to university a student needs to catch a train at 8:41a.m. every morning. Cycling to the station from home takes the student on average 14 minutes, with a standard deviation of 3 minutes. You can assume that the distribution of trip times is normally distributed and independent between days i) What is the probability that the student's cycle ride to the station will take more than 21 4 marks...
John, a healthy twenty-eight-year-old electrical engineer, was driving home from work one evening when he experienced a sudden stabbing pain in his right pectoral and right lateral axillary regions. He began to feel out of breath and both his respiratory rate and heart rate increased dramatically. As luck would have it, John passed a hospital each day on his way home and was able to get himself to the hospital’s emergency room. The emergency room physician listened to John’s breathing...
