    Question

    Givand is the following regression equation of a multiple interaction regression model: Ŷ=15−6.5X1+3X2−4X1X2\hat{Y} = 15-6.5X_{1}+3X_{2}-4X_{1}X_{2}.

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


    1. FALSE: Intercept = 15 ; Slope = -6.5
    2. FALSE: Intercept = 21 ; Slope = -6.5
    3. FALSE: Intercept = 15 ; Slope = -14.5
    4. TRUE: Intercept = 21 ; Slope = -14.5
