    Question

    Givand is the following regression equation of a multiple interaction regression model: Ŷ′=20−3.5X1+5X2−2X1X2\hat{Y}' = 20-3.5X_{1}+5X_{2}-2X_{1}X_{2}.

    Calculate the values of the intercept and slope that indicate the relationship betweand YY and X1X_{1} displays as X2=3X_{2} = 3.


    1. FALSE: Intercept=20 ; Slope=-3.5
    2. FALSE: Intercept=35 ; Slope=-3.5
    3. FALSE: Intercept=20 ; Slope=-9.5
    4. TRUE: Intercept=35 ; Slope=-9.5
