Required

a. Use the high-low method to develop a cost-estimating equation for total manufacturing costs. Interpret the meaning of the “fixed” costs and comment on the results.

b. Use the chart feature of a spreadsheet to develop a scatter graph of total manufacturing costs and total units produced. Use the graph to identify any unusual observations.

c. Excluding any unusual observations, use the high-low method to develop a cost-estimating equation for total manufacturing costs. Comment on the results, comparing them with the results in requirement (a).

d. Use simple regression analysis to develop a cost-estimating equation for total manufacturing costs.
What advantages does simple regression analysis have in comparison with the high-low method of cost estimation? Why must analysts carefully evaluate the data used in simple regression analysis?

e. Acustomer has offered to purchase 50 dining room tables for $220 per table. Management has asked your advice regarding the desirability of accepting the offer. What advice do you have for management? Additional analysis is required.
