Melissa Crupp is the new manager of the materials storeroom for Canton Manufacturing. Melissa
has been asked to estimate future monthly purchase costs for part #4599, used in two of Canton’s
products. Melissa has purchase cost and quantity data for the past nine months as follows:
Estimated monthly purchases for this part based on expected demand of the two products
for the rest of the year are as follows:
a) The computer in Melissa’s office is down and Melissa has been asked to immediately
provide an equation to estimate the future purchase cost for part # 4599. Melissa grabs
a calculator and uses the high-low method to estimate a cost equation. What equation
does she get?
b) Using the equation from requirement 1, calculate the future expected purchase costs for
each of the last three months of the year.
c) After a few hours Melissa’s computer is fixed. Melissa uses the first nine months of data
and regression analysis to estimate the relationship between the quantity purchased
and purchase costs of part #4599. The regression line Melissa obtains is as follows:
Use the regression results to calculate the expected purchase costs for October,
November, and December. Compare the expected purchase costs to the expected
purchase costs calculated using the high-low method in requirement 2. Comment on
your results.
