Question

Use the following multiple regression equation: Y = 50 - 2X1 + 3X2 Interpret the meaning of the slopes: a. For each one-unit increase in X2, Y will decrease by an estimated 2 units, holding X1 constant. b. For each one-unit increase in X1, Y will increase by an estimated 3 units, holding X2 constant. Interpret the meaning of the Y intercept: The Y-intercept of 50 estimates the value of Y when both X1 and X2 are 0.

          Use the following multiple regression equation:
Y = 50 - 2X1 + 3X2

Interpret the meaning of the slopes:
a. For each one-unit increase in X2, Y will decrease by an estimated 2 units, holding X1 constant.
b. For each one-unit increase in X1, Y will increase by an estimated 3 units, holding X2 constant.

Interpret the meaning of the Y intercept:
The Y-intercept of 50 estimates the value of Y when both X1 and X2 are 0.

Step 1

Interpret the meaning of the slopes: The given multiple regression equation is: $Y = 50 - 2X_1 + 3X_2$ The slope for $X_1$ is -2, and the slope for $X_2$ is 3. For each one-unit increase in $X_1$, the value of $Y$ will decrease by an estimated 2 units, holding Show more…
