urnal of Marketing mes for online orders, Exercise 2.880 (p. 88). Recall that a major apparel retailer has two distribution centers (DCs) to ulfill all its online orders - one located in the eastern United tates and one in the western United States. 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 = 5.22 and standard deviation o= .77. Similarly, ssume that the delivery time x for online orders fulfilled by the vestern DC is normally distributed with mean = 6.95 and standard deviation σ = .55. a. For online orders filled by the eastern DC, find P(z ≤ 5). b. For online orders filled by the eastern DC, find P(4≤ ≤7). NW c. For online orders filled by the eastern DC, find the value a, so that P(z > a) = .30. d. Repeat parts a-c for online orders filled by the western DC.
