Question
The estimated regression equation for a model involving two independent variables and 10 observations follows. = 22.1570 + 0.5906 x 1 + 0.4990 x 2
The estimated regression equation for a model involving two independent variables and 10 observations follows.
= 22.1570 + 0.5906x1 + 0.4990x2
(a)Interpret
b1in this estimated regression equation.b1 = 0.4990 is an estimate of the change in y corresponding to a 1 unit change in x1 when x2 is held constant.
b1 = 22.1570 is an estimate of the change in y corresponding to a 1 unit change in x1 when x2 is held constant.
b1 = 0.4990 is an estimate of the change in y corresponding to a 1 unit change in x2 when x1 is held constant.
b1 = 0.5906 is an estimate of the change in y corresponding to a 1 unit change in x1 when x2 is held constant.
b1 = 0.5906 is an estimate of the change in y corresponding to a 1 unit change in x2 when x1 is held constant.
Interpret
b2in this estimated regression equation.b2 = 0.4990 is an estimate of the change in y corresponding to a 1 unit change in x2 when x1 is held constant.
b2 = 0.4990 is an estimate of the change in y corresponding to a 1 unit change in x1 when x2 is held constant.
b2 = 0.5906 is an estimate of the change in y corresponding to a 1 unit change in x2 when x1 is held constant.
b2 = 0.5906 is an estimate of the change in y corresponding to a 1 unit change in x1 when x2 is held constant.
b2 = 22.1570 is an estimate of the change in y corresponding to a 1 unit change in x1 when x2 is held constant.
(b)Predict y when
x1 = 160 and x2 = 340.
