Use Computer Software to Find the Best Multiple Regression Equation $X _ { 1 } , X _ { 2 } , X _ { 3 }$

Multiple Choice

Use computer software to find the best multiple regression equation to explain the variation in the dependent variable, Y, in terms of the independent variables. $X _ { 1 } , X _ { 2 } , X _ { 3 }$
$\begin{array} { c c c } Y & X _ { 1 } & X _ { 2 } \\15 & 1.2 & 16 \\15 & 1.2 & 16 \\17 & 1.0 & 16 \\6 & 0.8 & 9 \\1 & 0.1 & 1 \\8 & 0.8 & 8 \\10 & 0.8 & 10 \\17 & 1.0 & 16 \\15 & 1.2 & 15 \\11 & 0.7 & 9 \\18 & 1.4 & 18 \\16 & 1.0 & 15 \\10 & 0.8 & 9 \\7 & 0.5 & 5 \\18 & 1.1 & 16\end{array}$
CORRELATION COEFFICIENT
$\begin{array} { l } \text { Y/ } X _ { 1 } = 0.886 \\\text { Y/ } X _ { 2 } = 0.965\end{array}$
COEFFICIENTS OF DETERMINATION
