Do not retype the information above. You should use this sheet as your data sheet and your solution should be on separate | | | | | | | | | | | |
sheets. | | | | | | | | | | | | | | | | | |
Part 2 should contain 2-simple regression tables, 1-multiple regression table, and 2-scattergraphs when you are done.--I have done one of the scattergraphs and simple regression using direct labor for you. | | |
Required: | | | | | | | | | | | | | | | | | |
1. Prepare 2 scattergraphs and 2 simple regression analyses***** to estimate the Manufacturing Overhead costs using each of the | | | | | | | | | | |
cost drivers above. Make sure you show the equation of the line and R-squared on each of your scattergraphs. | | | | | | | | | | | | |
I have gone ahead and developed the simple regression table and the scattergraph using Direct Manufacturing labor hours as the cost driver (I.e. independent variable) | | | | | |
You do not need to redo these, but you may want to use these as a verification that you know how to develop a scattergraph and a simple regression table. | | | | | | | |
The output and chart for your simple regression should be on separate sheets that should be named appropriately. | | | | | | | | | | | | |
Type the equation of the line under the regression output on each of the simple regression worksheets. | | | | | | | | | | | | | |
To make a scattergraph with data from nonadjacent columns highlight the X data (i.e. independent variable-cost driver) first and then hold down the | | | | | | | | | |
control (ctrl) key and highlight the Y data (i.e. the dependent variable-cost). | | | | | | | | | | | | | | |
If you have done your scattergraphs correctly the equation of the line and the R-squared should match the output you have on your regression table. | | | | | | | | | |
(i.e. R-squared, Intercept, and X Variable.) Hint: the Y(dependent) variable is the same in all your scattergraphs and regression analyses--which is Manufacturing overhead cost. | | | | | | |
| | | | | | | | | | | | | | | | | |
2. Prepare a multiple regression table using batches and direct labor hours for the independent variables. Do not try to prepare a scattergraph, since you cannot make a chart with multiple X's. | | | | | |
Using the output from the multiple regression, give the equation to estimate manufacturing overhead costs in terms of these | | | | | | | | | | | |
2 cost drivers. Type out the equation of the line on your multiple regression worksheet. | | | | | | | | | | | | | | |
X1 | Number of batches | | | | | | | | | | | | | | | | |
X2 | Direct Manufactuirng labor hours | | | | | | | | | | | | | | | |
| | | | | | | | | | | | | | | | | |
3. Assuming the following level of cost-driver volume, what is the estimated Manufacturing overhead | | | | | | | | | | | | | |
cost using simple regression for each of the cost drivers and using multiple regression. You should have | | | | | | | | | | | | | |
3 computations for this answer. I have completed one of the answers for you. You must use cell referencing from your regression tables to compute the estimated cost to earn credit for part 3. | | | | |

4. Using the simple and multiple regression analyses output tables, what independent variable(s) would you recommend | | | | | | | | | | | |
to estimate the Indirect Manufacturing Overhead Costs? Why? Your response should be at least 75 words and discuss the R-Squared. | | | | | | | | | | |
