Scatter Diagrams and High-Low Cost Estimation Assume the local Pearle Vision has the following information on the number of sales orders received and order-processing costs. Month Sales Orders Order Processing Costs 1 2 3,000 1,500 $49,620 30,225 3 4,400 72.420 4. 2.800 49.140 S 2.300 41,865 6 1,200 7 2,000 25,860 37,500 NOTE: Round variable cost per unit answers to two decimal places, if appropriate. (a.) Use information from the high- and low-volume months to develop a cost-estimating equation for monthly order-processing costs. $ 15,400 x 8400 + M.Ssx Correct (b.) Plot the data on a scatter diagram. Using the information from representative high-and low-volume months, develop a cost estimating equation for monthly production costs. If needed, an Excel worksheet is provided in the following link in order to create the scatter diagram: Scatter Diagram $ 15,622 X 23.93 XX 19
