Deck 5: Cost Estimation

Question 1

The engineering method of determining cost behavior is particularly useful for new activities or products.

Answer 1

True

Question 2

Cost behavior is the most important characteristic for managerial decision making.

Answer 2

True

Question 3

In general,cost behavior results are likely to differ between the engineering method and the account analysis method.

Answer 3

True

Question 4

A scattergraph is useful for identifying outliers/irrelevant data points.

Question 5

The account analysis method is more subjective than other cost estimation methods because it relies heavily on the personal judgment and experience of accountants.

Question 6

Because outliers are extreme data points,they can be included in the regression analysis and not significantly affect the results.

Question 7

The relevant range represents those activity levels for which valid cost relationships have been observed.

Question 8

The linear cost estimate tends to understate the slope of the cost line in ranges close to capacity.

Question 9

One advantage that regression techniques have over other cost estimation methods is it generates information that can be used to determine how well the estimated cost equation will predict future costs.

Question 10

One way to control the effects of a nonlinear relation between total costs and volume is to reduce the relevant range.

Question 11

The quality of the cost equation depends on collecting appropriate data.

Question 12

Cost estimates using regression analysis are always more accurate and dependable than cost estimates using the scattergraph methods.

Question 13

A basic assumption of most cost estimation methods is cost behavior patterns are linear within the relevant range.

Question 14

One disadvantage of the high-low method is the highest and lowest points may not be representative of normal operating activities.

Question 15

In general,accounting records accumulate cost information according to its behavior (i.e. ,variable and fixed).

Question 16

Different cost estimations methods may produce different cost equations,even when using the same set of data.

Question 17

One advantage of the engineering method is that it does not require data from prior periods to estimate cost behavior.

Question 18

One advantage of the account analysis method for estimating cost behavior is that it includes actual work conditions.

Question 19

In general,the use of multiple independent variables increases the proportion of the variation in the dependent variable explained by the cost equation.

Question 20

In general,the account analysis method focuses on the underlying relationship between cost and activities from the previous period.

If the controller uses regression analysis to estimate costs,the cost equation for electricity cost is:

A) Cost = $1,425.18 + $12.00 × Machine-hours.
B) Cost = $3,726.88 + $1,682.82 × Machine-hours.
C) Cost = $1,682.82 + $0.49 × Machine-hours.
D) Cost = $3,726.88 + $5.77 × Machine-hours.

Question 79

Which of the following may be used to estimate how inventory warehouse costs are affected by both the number of shipments and the weight of the material handled? (CPA adapted)

A) Economic order quantity analysis.
B) Probability analysis.
C) Correlation analysis.
D) Multiple regression analysis.

Question 80

Thane Company is interested in establishing the relationship between electricity costs and machine hours.Data have been collected and a regression analysis prepared using Excel.The monthly data and the regression output follow: $$\begin{array} { | l | r | r | } \hline \text { Month } & \text { Machine Hours } & \text { Electricity Costs } \\\hline \text { January } & 2,500 & 18,400 \\\hline \text { February } & 2,900 & 21,000 \\\hline \text { March } & 1,900 & 13,500 \\\hline \text { April } & 3,100 & 23,000 \\\hline \text { May } & 3,800 & 28,250 \\\hline \text { June } & 3,300 & 22,000 \\\hline \text { Juby } & 4,100 & 24,750 \\\hline \text { August } & 3,500 & 22,750 \\\hline \text { September } & 2,000 & 15,500 \\\hline \text { October } & 3,700 & 26,000 \\\hline \text { November } & 4,700 & 31,000 \\\hline \text { December } & 4,200 & 27,750 \\\hline\end{array}$$

If the controller uses regression analysis to estimate costs,the estimate of the variable portion of electricity cost is:

A) Cost = $11.70 × Machine-hours.
B) Cost = $0.93 × Machine-hours.
C) Cost = $5.77 × Machine-hours.
D) Cost = $0.49 × Machine-hours.
