Exercise 5-45 (Algo) Interpretation of Regression Results: Multiple Choice (LO 5-5) Cortez Company is planning to introduce a new product that will sell for $107 per unit. The following manufacturing cost estimates have been made on 20,000 units to be produced the first year Direct materials Direct labor $980,000 548,448 (= $18 per hour - 30,000 hours) Manufacturing overhead costs have not yet been estimated for the new product, but monthly data on total production and overhead costs for the past 24 months have been analyzed using simple linear regression. The following results were derived from the simple regression and provide the basis for overhead cost estimates for the new product Simple Regression Analysis Results Dependent variable-Factory overhead costs Independent variable-Direct lobor-hours Computed values Intercept $100,000 Coefficient on Independent variable 5.00 Coefficient of correlation .928 R2 .861 $ Requirea .. What percentage of the variation in overhead costs is explained by the independent variable? 86.10% 94.70% 103-30% 7750% None of the above b. What is the total overhead cost for an estimated activity level of 70.000 direct labor-hours? $450,000 O $460,000 $440,000 $470.000 O None of the above c. How much is the variable manufacturing cost per unit, using the variable overhead euthated by the regression (ossuming that direct materials and direct labor are variable costs)? O $80.00 $88.00 $96.00 $72.00 None of the above d. What is the expected contribution margin per unit to be earned during the first year on 20,000 units of the new product? (Assume that all marketing and administrative costs are fixed.) O $27.00 O $30.00 O $32.00 O $24.00 O None of the above e. What is the manufacturing cost equation implied by these results? Total cost $540,000 + ($5.00 * Number of units) Total cost = $100,000 + ($107.00 * Number of units) Total cost = $100,000 + ($18.00 Number of units) O None of the above
