Use Computer Software to Find the Best Regression Equation to Explain

Use computer software to find the best regression equation to explain the variation in the dependent variable, Y, in terms of the independent variables, X1, X2, X3
- $\begin{array}{ccc}\mathrm{Y} & \mathrm{X}_{1} & \mathrm{X}_{2} \\15 & 1.2 & 16 \\15 & 1.2 & 16 \\17 & 1.0 & 16 \\6 & 0.8 & 9 \\1 & 0.1 & 1\\8 & 0.8 & 8 \\10 & 0.8 & 10 \\17 & 1.0 & 16 \\15 & 1.2 & 15 \\11 & 0.7 & 9 \\18 & 1.4 & 18 \\16 & 1.0 & 15 \\10 & 0.8 & 9 \\7 & 0.5 & 5 \\18 & 1.1 & 16\end{array}$
CORRELATION COEFFICIENT
$\begin{array}{l}\mathrm{Y} / \mathrm{X}_{1}=.886 \\\mathrm{Y} / \mathrm{X}_{2}=.965\end{array}$
COEFFICIENTS OF DETERMINATION
$\begin{array}{c}\mathrm{Y} / \mathrm{X}_{2}=.932 \\Y / \mathrm{X}_{2}, \mathrm{X}_{1}=.943\end{array}$

A) $\hat { Y } = .42 + .99 \mathrm { X } _ { 2 }$
B) $\hat { Y } = 1.38 - 5.53 X _ { 1 } + 1.33 X _ { 2 }$
C) $\hat { \mathrm { Y } } = - .42 + 14.07 \mathrm { X } _ { 1 }$
D) $\hat { Y } = 1.25 - 1.55 X _ { 1 } + 5.79 X _ { 2 }$
