Question

19. Suppose that customer arrivals at a shop are modeled by Poisson process with rate of ? = 5 per hour. Let T be the time of the first arrival. The probability that the first customer arrives during the first 15 minutes soon after the shop opens for business is closest to: (a) 0.63 (b) 0.29 (c) 0.05 (d) 0.71 (e) 0.37 20. In a certain neighborhood, the height of women is normally distributed with mean 63 and standard deviation 3, while the height of men is normally distributed with mean 67 and standard deviation 4. You choose a women and a man at random from the neighborhood. The probability that the their heights are within 2 inches of each other is closest to: (a) 0.13 (b) 0.23 (c) 0.54 (d) 0.77 (e) .87
