Based on the study, we can assume that the delivery time x (in business days) for online orders fulfilled by the eastern DC is normally distributed with mean u = 5.22 and standard deviation o = .77. Similarly, assume that the delivery time x for online orders fulfilled by the western DC is normally distributed with mean u = 6.95 and standard deviation o = .55. a. For online orders filled by the eastern DC, find Pac a) = .30. d. Repeat parts a-c for online orders filled by the western DC
