Scatter diagrams and high-low cost estimationassume the local pearle vision has the following information on the number of sales orders received and order-processing costs. month sales orders order-processing costs1 3,000 $ 49,6202 1,500 30,2253 4,400 72,4204 2,800 49,1405 2,300 41,8656 1,200 25,8607 2,000 37,500required(a.) use information from the high- and low-volume months to develop a cost-estimating equation for monthly order-processing costs.(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: month sales orders order-processing costs1 3,000 $ 82,7002 1,500 50,3753 4,400 120,7004 2,800 81,9005 2,300 69,7756 1,200 43,1007 2,000 62,500
