Question

Use the following multiple regression equation. Y_i = 40 - 7X_1i + 3X_2i a. Interpret the meaning of the slopes. b. Interpret the meaning of the Y intercept a. Interpret the meaning of the slopes For each one-unit increase in X_1. Y will an estimate units, holding constant. For each one-limit increase in X_2, Y will an estimated units, holding constant b. Interpret the meaning of the Y intercept. Choose the correct answer below. A. The Y-intercept 40 estimates the value of Y when both X_1 and X_2 are 0. B. The Y-intercept 40 estimates the value of Y when X_2 is 0. C. The Y-intercept 7 estimates the value of Y when both X_1 and X_2 are 0. D. The Y-intercept 7 estimates the value or Y when X_1is 0. E. The Y-intercept 40 estimates the value of Y when X_1 is 0. F. The Y-intercept 3 estimates the value of Y when both X_1 and X_2 are 0. G. The Y-intercept 3 estimates the value of Y when X_2 is 0.

Explanation / Answer

a) for each one unit increases in X1, Y will decrease an estimated 7 units holding X2 constant, For each one unit increases in X2, Y will increase an estimated 3 units holding X1 constant.

b)A) The Y intercept 40 estimates the value of Y When both X1 and X2 0.
