The Perize Corporation used regression analysis to predict the annual cost of indirect materials. The results were as follows:

Indirect Materials Cost Explained by Units Produced
Constant	$15,685
Standard error of Y estimate	$3,500
r2	0.7832
Number of observations	20
X coefficient(s)	10.25
Standard error of coefficient(s)	2.1876

A.

Y = $12,285 + $10.25X

B.

Y = $3,500 + $5.15X

C.

Y = $15,685 + $10.25X

D.

Y = $19,185 + $4.48X
