Exam 3: Cost Behavior

are assumed to be the sole drivers of a traditional cost management system.

The industrial engineering method is used to determine which activities, and in what amounts, are necessary to complete a process.

A nursing home requires one nurse for each six patients. This is an example of a

The Ladder Company wants to develop a cost estimating equation for its monthly cost of electricity. It has the following data: Using the high-low method, which of the following is the best equation?

Cumulative average-time curve assumes the cumulative average time per unit decreases by a constant percentage each time the cumulative quantity of units produced doubles.

Lowell & Company has the following cost data pertaining to the production of small desks: Required: a. Plot the preceding direct labor costs and overhead costs using the scatterplot method. Overhead costs should be on the vertical axis. b. Compute the fixed and variable components of the overhead costs using the high-low method.

What does a correlation coefficient near +1 mean?

Figure 3-1 Sonor Systems undertakes its own machine maintenance. The depreciation on the equipment is $20,000 per year and operating cost is $2 per machine hour. Last year 275,000 machine hours were used to produce 100,000 units. -See Figure 3-1. What is the total maintenance cost per unit produced?

What does a correlation coefficient near -1 mean?

The direct material cost is $20,000 when 2,000 units are produced. What is the direct material cost for 2,500 units produced?

Figure 3-7 The following computer printout estimated overhead costs using regression: Please find the following statistical table During the last accounting period 10,000 DLH were worked . -Refer to Figure 3-7. Find the t-value for a 90 percent confidence level.

Figure 3-3 The Sandoval Company has four process engineers that are each able to process 1,500 design changes. Last year 5,250 design changes were produced by the four engineers. Each engineer is paid $60,000 per year -The method for analyzing cost behavior that generally classifies general ledger accounts is

The graph showing the relationship between activity costs and drivers/outputs is called the __________ .

The appropriate range for the coefficient of correlation (r) is

Apparent Corp. has developed the following information on product costs and inventories for a three-month period: Based on managerial judgment, the best predictor of manufacturing costs is

The drivers that explain changes in costs as units produced change are called:

In the method of least squares, each single measure of closeness is first squared. Squaring the deviations avoids problems caused by a mix of positive and negative numbers.

Figure 3-6 The Stanford Company incurred the following maintenance cost during a five month period: -Refer to Figure 3-6. Using a computer or calculator, compute the estimate of the fixed portion of maintenance costs using the method of least squares. Rounded to dollars, this value would be

Committed resources

Figure 3-9 Hereford Company is planning to introduce a new product with an 80 percent learning rate for production for batches of 1,000 units. The variable labor costs are $30 per unit for the first 1,000-unit batch. Each batch requires 100 hours. There are $10,000 in fixed costs not subject to learning. -Refer to Figure 3-9. What is the batch unit time (labor hours) to produce 2,000 units based on the cumulative average time learning curve?
