An important application of regression analysis in accounting isin the estimation of cost. By collecting data on volume and costand using the least squares method to develop an estimatedregression equation relating volume and cost, an accountant canestimate the cost associated with a particular manufacturingvolume. Consider the following sample of production volumes andtotal cost data for a manufacturing operation.
| Production Volume (units) | Total Cost ($) |
400 $4300
450 $5300
550 $5700
600 $6200
700 $6700
750 $7300
