1. These are among the methods of segregating fixed cost and variable costs except:

1. Simple regression analysis
2. Scattergraph
3. Breakeven method
4. High-low method

2. All of the following are assumptions underlying the validity of linear regression output except

1. The errors are normally distributed and their mean is zero.
2. Certainty.
3. The variance of the errors is constant.
4. The independent variables are not correlated with each other. (cma)

3. In determining cost behavior in business, the cost function is often expressed as

Y = a + bx. Which one of the following cost estimation methods should not be used in estimating fixed and variable costs for the equation?

1. Graphic method.
2. High-and-low point method.
3. Simple regression
4. Multiple regressions. cma)

4. Simple regression analysis involves the use of

Dependent variables Independent variables

a. One None

b. One One

c. One Two

d. None Two (cma/aicpa)

5. Regression analysis

1. Estimates the independent cost variable.
2. Uses probability assumptions to determine total project costs.
3. Estimated the dependent cost variable.
4. Ignores the coefficient of determination.
5. Encompasses factors outside the relevant range. (cma)
