4.99 DELIVERY TIMES FOR ONLINE ORDERS. Refer to the PUTIN Journal of Marketing Research (October 2019) study of delivery MERE times for online orders, Exercise 2.88 (p. 88). Recall that a PETENZEN P SEM NEM MINDEN PM WW major apparel retailer has two distribution centers (DCs) to MEN WHEN SEHEME MEMMERTER HE E fulfill all its online orders - one located in the eastern United IN MEMENUHI NZI PREZE States and one in the western United States. Based on the study, P C PM M 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, assume that the delivery time x for online orders fulfilled by the PER western DC is DC is normally distributed with mean µ = 6.95 and P standard deviation σ = .55. a. For online orders filled by the eastern DC, find P(a ≤ 5). b. For online orders filled by the eastern DC, find P(4≤ ≤7).
