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

TEM W S
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.

western DC.

A least squares regression model performed to predict the selling price of houses found the following equation: Pricê = 169.328+35.3Area + 0.718Lotsize - 6543Age where Price is in dollars, Area is in square feet, Lotsize is in square feet, and Age is in years. The R2 is 0.92. One of the following interpretations is correct. Which is it? Explain why. a.) Each year a house Ages, it is worth $6543 less. b.) Every extra square foot of Area is associated with an additional $35.30 in average price, for houses with a given Lotsize and Age. c.) Every dollar in price means Lotsize increases 0.718 square feet. d.) This model fits 92% of the data points exactly.
