108.A cost that is part selling cost and part manufacturing cost is referred to as a mixed cost.



True False

109.When selecting the high and low observations under the high-low method of analyzing mixed costs, the selection should be based on the dependent variable (cost).



True False

110.When using least-squares regression to determine variable and fixed costs, the r-square refers to the degree to which the change in the dependent variable can be explained by a change in the independent variable.



True False

111.An advantage of using the scattergraph method over the high-low method is that all points of data are used in determining the cost line.



True False

112.Multiple regression analysis should be performed when a single independent variable influences multiple dependent variables.



True False

113.In regression analysis, an r-square value of one indicates that there is a perfect fit between the independent and dependent variables.



True False

114.A disadvantage of the high-low method is that the high point and low point may not be representative of the total data set available.



True False
