In the Model Y = β0 + β1x + β2d

Question 63

Multiple Choice

In the model y = β0 + β1x + β2d + β3xd + ε, for a given x and d = 1, the predicted value of y is given by ________.


A) In the model y = β<sub>0</sub> + β<sub>1</sub>x + β<sub>2</sub>d + β<sub>3</sub>xd + ε, for a given x and d = 1, the predicted value of y is given by ________. A) = b<sub>0</sub> + b<sub>1</sub>x + b<sub>2</sub> + b<sub>3</sub>x B) = b<sub>0</sub> + b<sub>2</sub> + b<sub>1</sub>x + b<sub>3</sub>x C) = (b<sub>0</sub> + b<sub>2</sub>) + (b<sub>1</sub> + b<sub>3</sub>) x D) All of these choices are correct. = b0 + b1x + b2 + b3x
B) In the model y = β<sub>0</sub> + β<sub>1</sub>x + β<sub>2</sub>d + β<sub>3</sub>xd + ε, for a given x and d = 1, the predicted value of y is given by ________. A) = b<sub>0</sub> + b<sub>1</sub>x + b<sub>2</sub> + b<sub>3</sub>x B) = b<sub>0</sub> + b<sub>2</sub> + b<sub>1</sub>x + b<sub>3</sub>x C) = (b<sub>0</sub> + b<sub>2</sub>) + (b<sub>1</sub> + b<sub>3</sub>) x D) All of these choices are correct. = b0 + b2 + b1x + b3x
C) In the model y = β<sub>0</sub> + β<sub>1</sub>x + β<sub>2</sub>d + β<sub>3</sub>xd + ε, for a given x and d = 1, the predicted value of y is given by ________. A) = b<sub>0</sub> + b<sub>1</sub>x + b<sub>2</sub> + b<sub>3</sub>x B) = b<sub>0</sub> + b<sub>2</sub> + b<sub>1</sub>x + b<sub>3</sub>x C) = (b<sub>0</sub> + b<sub>2</sub>) + (b<sub>1</sub> + b<sub>3</sub>) x D) All of these choices are correct. = (b0 + b2) + (b1 + b3) x
D) All of these choices are correct.
