Big Mikes, a large hardware store, has gathered data on its overhead activities and associated costs for the past 10 months. Nizam Sanjay, a member of the controller's department, believes that overhead activities and costs should be classified into groups that have the same driver. He has decided that unloading incoming goods, counting goods, and inspecting goods can be grouped together as a more general receiving activity, since these activities are all driven by the number of receiving orders. The 10 months of data shown below have been gathered for the receiving activity Month Receiving Orders 1,000 1,340 1,150 900 Receiving Costs 12,170 12,940 13,750 9,930 15,070 14,145 16,640 14 14,800 1 7,940 15,000 0 1,350 1,400 1,600 1,490 1,800 1,700 09 8 1800 Required: 1.
