Question

In the packaging department of a large aircraft parts distributor, a fairly reliable estimate of
packaging and processing costs can be determined by knowing the weight of an order. Thus, the
weight is a cost driver that accounts for a sizable fraction of the packaging and processing costs
at this company. Data for the past 10 orders are given as follows:

Estimate the b0 and b1 coefficients, and determine the linear regression equation to fit
these data.
b. What is the correlation coefficient (R)?
c. If an order weighs 250 lb, how much should it cost to package and process it?
а.
