(A) Using Excel, generate a 3D graph of the following regression equation: Y#770;=5+2.6X_1-1.
Question: (A) Using Excel, generate a 3D graph of the following regression equation:
\[\hat{Y}=5+2.6{{X}_{1}}-1.6{{X}_{2}}+0.5{{X}_{1}}{{X}_{2}}\]
(B) Based on the graph, (roughly) describe how the effect of \({{X}_{1}}\) on \(\hat{Y}\) when X2 = 0 differs from the effect of \({{X}_{1}}\) on \(\hat{Y}\) when X2 = 10.
(C) What is the precise effect of a one-unit increase in X2 on \(\hat{Y}\) when X1 = 0? What is the precise effect of a one-unit increase in X2 on \(\hat{Y}\) when X1 = 7?
