An important application of regression analysis in accounting is in the estimation of cost. By collecting data on volume and cost and using the least squares method to develop an estimated regression equation relating volume and cost, an accountant can estimate the cost associated with a particular manufacturing volume. In the Microsoft Excel Online file below you will find a sample of production volumes and total cost data for a manufacturing operation. Conduct a regression analysis to explore the relationship between total cost and production volume and then answer the questions that follow. Due to a recent change by Microsoft you will need to open the XLMiner Analysis ToolPak add-in manually from the home ribbon. Screenshot of Toolpak Open spreadsheet a. Compute b1 and b0( to 1 decimal): Complete the estimated regression equation (to:1 decimal). Complete the estimated regression equation (to.1 decimal). y= b. According to this model, what is the change in cost (in dollars) for every unit produced (to 1 decimal)? c. Compute the coefficient of determination (to 3 decimals). Note: repott r2 between 0 and 1 . What percentage of the variation in total cost can be explained by the production volume fro 1 decimaly? d. The combany's production schedule chons 500 units must be grodeiced next month. What is the estimated total cout for this operation (to the nearest whole number)? An important application of regression analysis in accounting is in the estimation of cost.
