Consider the Model Y = β0 + β1x + β2d

Question 47

Multiple Choice

Consider the model y = β0 + β1x + β2d + ε,where x is a quantitative variable and d is a dummy variable.For d = 1,the predicted value of y is computed as:


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.For d = 1,the predicted value of y is computed as: 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> D) = 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.For d = 1,the predicted value of y is computed as: 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> D) = b0 + b1x
C) 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.For d = 1,the predicted value of y is computed as: 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> D) = (b0 + b1) x + b2
D) 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.For d = 1,the predicted value of y is computed as: 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> D)
