Question

For this problem, use the multiple regression equation below to complete parts (a) and (b). Y cap_i = 10 + 5X_1t + 3X_2t Interpret the meaning of the slopes. A. If x_1 increases one unit, Y increases 5 units. If X_2 increases one unit, Y increases 3 units. B. if X_2 is constant, when x_1 increases one unit, Y increases 3 units. If X_1 is constant, when X_2 increases one unit, Y increases 5 units. C. If X_2 is constant, when X_1 increases one unit, Y increases 5 units. If X_1 is constant, when X_2 increases one unit, Y increases 3 units, D. If x_1 increases one unit, Y increases 3 units. If x_2 increases one unit, Y increases 5 units. Interpret the meaning of the Y intercept. A. The Y intercept 5 is the estimate of the mean value of Y if x_1 and X_2 are both B. The Y-intercept 10 is the estimate of the mean value of Y if X_1 and X_2 are both 0 c. The Y intercept 5 is the estimate of the mean value of Y if X_1 is 0 D. The Y-intercept 10 is the estimate of the mean value of Y if X_1 is 0.

Explanation / Answer

a) Correct Answer: Option (C)

b) Correct Answer: Option (B)

since

If X1 = X2 = 0 then

Ycap = 10 + 5(0) + 3(0) = 10
