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.

4.99 DELIVERY TIMES FOR ONLINE ORDERS. Refer to the
Journal of Marketing Research (October 2019) study of delivery
times for online orders, Exercise 2.88 (p. 88). Recall that a
major apparel retailer has two distribution centers (DCs) to
fulfill all its online orders - one located in the eastern United

States 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 = .77. Similarly,
assume that the delivery time x for online orders fulfilled by the
western DC is normally distributed with mean μ = 6.95 and
standard deviation o- .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.
