A) Consider the model y = β<sub>0 </sub>+ β<sub>1</sub>x + β<sub>2</sub>d + ε, where x is a quantitative variable and d is a dummy variable. When d = 1, the predicted value of y ________. A) = b<sub>0 </sub>+ b<sub>1</sub>x + b<sub>2</sub>x B) = b<sub>0 </sub>+ b<sub>1</sub>x C) = (b<sub>0 </sub>+ b<sub>1</sub>) x + b<sub>2</sub> <sub> D) </sub> <sub> </sub> = (b<sub>0 </sub>+ b<sub>2</sub>) + b<sub>1</sub>x = b0 + b1x + b2x
B) Consider the model y = β<sub>0 </sub>+ β<sub>1</sub>x + β<sub>2</sub>d + ε, where x is a quantitative variable and d is a dummy variable. When d = 1, the predicted value of y ________. A) = b<sub>0 </sub>+ b<sub>1</sub>x + b<sub>2</sub>x B) = b<sub>0 </sub>+ b<sub>1</sub>x C) = (b<sub>0 </sub>+ b<sub>1</sub>) x + b<sub>2</sub> <sub> D) </sub> <sub> </sub> = (b<sub>0 </sub>+ b<sub>2</sub>) + b<sub>1</sub>x = b0 + b1x
