Exhibit 13-11
Below you are given a partial computer output based on a sample of 25 observations.
$\begin{array}{lcc}&\text { Coefficient }&\text { Standard Error }\\\text { Constant } & 145 & 29 \\\mathrm{X}_{1} & 20 & 5 \\\mathrm{X}_{2} & -18 & 6 \\\mathrm{X}_{3} & 4 & 4\end{array}$
-Refer to Exhibit 13-11. The estimated regression equation is

A) Y = ?? + ??X1 + ?2X2 + ?3X3 + ?
B) EY) = ?? + ??X1 + ?2X2 + ?3X3
C) =29+5X1+6X2+4X3
D) =145+20X1 - 18X2+4X3
