The following information applies to the questions displayed below.) Davis Stores sells clothing in 15 stores located around the southwestern United States. The managers at Davis are considering expanding by opening new stores and are interested in estimating costs in potential new locations. They believe that costs are driven in large part by store volume measured by revenue. During a discussion, one of the managers suggests that number of employees might be better at explaining cost than store revenues. As a result of that suggestion, managers collected the following information from last year's operations (revenues and costs in thousands of dollars): Store 101 102 103 104 105 106 107 10B 109 110 111 112 113 114 115 Costa $4,868 3,936 4,916 1,697 5,074 5,721 5,773 1,818 6.012 1,988 2,357 6,226 1,874 2, 744 3,094 Employees 29 43 54 25 54 41 54 26 57 26 30 58 27 26 54 Revenues $2,747 4,709 4,516 6, 780 2,627 3,317 6,865 4,530 5,643 2,984 3,046 6,683 2,420 3,625 6,092 Required a.

Use the results of your high-low analysis to estimate the cost for a store with 54 employees. (Do not round your intermediate calculations. Negative amounts should be indicated by a minus sign. Round your answer to the nearest whole number (in thousands of dollars).) Store cost c. Prepare a scattergraph between store cost and employees. Instructions: 1.
