Use the following multiple regression equation. , = 70 - 2X; + 4X2i 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,, Y will an estimated units, holding constant. For each one-unit increase in X,, Y will V an estimated units, holding constant b. Interpret the meaning of the Y intercept. Choose the correct answer below. O A. The Y-intercept 4 estimates the value of Y when X, is 0. O B. The Y-intercept 4 estimates the value of Y when both X, and X are 0. OC. The Y-intercept 2 estimates the value of Y when X, is 0. O D. The Y-intercept 70 estimates the value of Y when X, is 0. O E. The Y-intercept 70 estimates the value of Y when both X, and X, are 0. OF. The Y-intercept 2 estimates the value of Y when both X, and X, are 0. O G. The Y-intercept 70 estimates the value of Y when X, is 0.
