Complete a three-part assessment in a supplied Excel template in which you apply regression analysis to decision making, determine unit costs, and analyze overhead using a predetermined rate.
Introduction
Cost estimation involves the use of a familiar accounting and finance tool: cost/benefit analysis. Through cost/benefit analysis, managers can explore and evaluate multiple alternatives to choose the one most beneficial to the organization's bottom line. When evaluating alternatives, it is imperative that comparisons are "apples to apples;" that is, when estimating costs across multiple alternatives, cost data must be expressed in terms of variable and fixed costs, along with the drivers of these costs.
In Assessment 2, you will present information about estimating costs using multiple analysis methods, such as account analysis, statistical analysis, and regression output. Upon completion of this assessment, you will have demonstrated an understanding of the role that cost estimation plays in capturing and using existing accounting information for decision making by managers.
This assessment includes alternative cost systems, beginning with product and service costs.
Before beginning this assessment, take time to review the following topics:
Regression analysis.
Operations costing.
Overhead analysis.

Assessment 2 Part 1: Interpretation of Regression Results
Part 1 Scenario
Your company provides various delivery services. Management wants to know the volume of a particular delivery that would generate $11,000 per month in operating profits before taxes. The company charges $22 per delivery.
The controller’s office has estimated overhead costs at $9,900 per month for fixed costs and $12 per delivery for variable costs. You believe that the company should use regression analysis. Your analysis shows the results to be:
Monthly overhead=$26,501+$10.70 per delivery.
Your estimate was based on the following data:
Data Used for Estimate
Month
Overhead Costs
Number of Deliveries
1
$159,630
$12,510

$183,990
$15,060

$180,630
$14,730
Complete the following:
The company controller is somewhat surprised that your cost estimates differ so greatly from the controller's estimates. You have been asked to recheck your work and see if you can figure out why.
Analyze the data and your results and state your reasons for supporting or rejecting your cost equation. Show all calculations.
Write a one-page report informing management of the correct volume that will generate $11,000 per month in operating profits before taxes. The report should include an introduction, operating cost summary, proposed volume to generate desired operating profits before taxes, and a conclusion.
Assessment 2 Part 2: Operations Costing
Compute the cost per unit of the two different models of calculators produced by Nevada Instruments based on the operations costing. Show all calculations.
Part 2 Scenario
Nevada Instruments manufactures two models of calculators. The finance model is the Financial 5 and the scientific model is the Scientific 6. Both models are assembled in the same plant and require the same assembly operations. The difference between the models is in the cost of the parts.
The following data are available for August:
