Chapter 13.4, Problem 16P
Suppose that a regional express delivery service company wants to estimate the cost of shipping a package (Y) as a function of cargo type, where cargo type includes the following possibilities: fragile, semifragile, and durable. Costs for 15 randomly chosen packages of approximately the same weight and same distance shipped, but of different cargo types, are provided in the file P13_16.xlsx.
- a. Estimate a regression equation using the given sample data, and interpret the estimated regression coefficients.
- b. According to the estimated regression equation, which cargo type is the most costly to ship? Which cargo type is the least costly to ship?
- c. How well does the estimated equation fit the given sample data? How might the fit be improved?
- d. Given the estimated regression equation, predict the cost of shipping a package with semifragile cargo.

IM.82 A distributor of industrial equipment purchases specialized compressors for use in air conditioners. The regular price is $50, however, the manufacturer of this compressor offers quantity discounts per the following discount schedule:
Option Plan Quantity Discount
A 1 - 299 0%
B 300 - 1,199 0.50%
C 1,200+ 1.50%
The distributor pays $56 each time it places an order with the manufacturer. Holding costs are negligible (none) but they do earn 10% annual interest on all cash balances (meaning there will be a financial opportunity cost when they put cash into inventory). Annual demand is expected to be 10,750 units.
When there is no quantity discount (Option Plan A, the first row of the schedule listed above), what is the adjusted order quantity? (Display your answer to the nearest whole number.)

Excel Please. The workload of many areas of banking operations varies considerably based on time of day. A variable capacity can be achieved effectively by employing part-time personnel. Because part-timers are not entitled to all the fringe benefits, they are often more economical than full-time employees. Other considerations, however, may limit the extent to which part-time people can be hired in a given department. The problem is to find an optimal workforce schedule that would meet personnel requirements at any given time and also be economical.
Some of the factors affecting personnel assignments are listed here:
The bank is open from 9:00am to 7:00pm.
Full-time employees work for 8 hours (1 hour for lunch included) per day. They do not necessarily have to start their shift when the bank opens.
Part-time employees work for at least 4 hours per day, but less than 8 hours per day and do not get a lunch break.
By corporate policy, total part-time personnel hours is limited…
