Unformatted text preview: 6-44 (35 MINUTES) 1. The regression equation's intercept on the vertical axis is \$190. It represents the portion of indirect material cost that does not vary with machine hours when operating within the relevant range. The slope of the regression line is \$5 per machine hour. For every machine hour, \$5 of indirect material costs are expected to be incurred. 2. Estimated cost of indirect material at 850 machine hours of activity: S = \$190 + (\$5 × 850) = \$4,440 3. Several questions should be asked: (a) Do the observations contain any outliers, or are they all representative of normal operations? (b) Are there any mismatched time periods in the data? Are all of the indirect material cost observations matched properly with the machine hour observations? (c) Are there any allocated costs included in the indirect material cost data? (d) Are the cost data affected by inflation? 4.

April \$1,300 5,900  (1,350) \$5,850 High-low method: Variable cost per machine hour = difference in cost levels difference in activity levels = \$5,850 − \$4,200 \$1,650 = = \$5.50 per machine hour 1,000 − 700 300 August \$1,000 6,200  (3,000) \$4,200 Fixed cost per month: Total cost at 1,000 hours...............................................................................

Fixed cost....................................................................................................... \$5,850  5,500 \$  350 Equation form: Indirect material cost = \$350 + (\$5.50 × machine hours) 6. The regression estimate should be recommended because it uses all of the data, not just two pairs of observations when developing the cost equation. ...
