Short Answer

The Partridge Corporation used regression analysis to predict the annual cost of indirect materials. The results were as follows: Indirect M aterials Cost
Explained by Units Produced
$\begin{array}{cc}\text { Constant } & \$ 19,885 \\\text { Standard error of Y estimate } & \$ 7,560 \\\text { R - squared } & 0.7832 \\\text { No. of ob servations } & 22\\\text { Degrees of freedom } & 20 \\X \text { coefficient(s) } & 9.75 \\\text { Stand ard error of coefficient }(s) & 2.1876\end{array}$ The linear cost function is: $A$ ) $Y=$
$\$ 7,560+\$ 2.19 X$
$\text { B) } \mathrm{Y}=\$ 7,560+\$ 9.75 \mathrm{X}$
$\text { C) } \mathrm{Y}=\$ 19,885+\$ 9.75 \mathrm{X}$
$\text { D) None of theseanswers is correct }$
