Extracted text: The estimated regression equation for a model involving two independent variables and 10 observations follows. ý = 27.1870 + 0.5908x1 + 0.4930x2 (a) Interpret b, in this estimated regression equation. b1 = 0.5908 is an estimate of the change in y corresponding to a 1 unit change in x, when X1 is held constant. b1 = 0.5908 is an estimate of the change in y corresponding to a 1 unit change in x, when X2 is held constant. b1 = 0.4930 is an estimate of the change in y corresponding to a 1 unit change in x, when X2 is held constant. O b1 = 27.1870 is an estimate of the change in y corresponding to a 1 unit change in x, is held constant. when X2 b1 = 0.4930 is an estimate of the change in y corresponding to a 1 unit change in x, when X1 is held constant. Interpret b, in this estimated regression equation. = 0.5908 is an estimate of the change in y corresponding to a 1 unit change in x, O b2 is held constant. when X2 b2 = 0.5908 is an estimate of the change in y corresponding to a 1 unit change in x, when X1 is held constant. = 27.1870 is an estimate of the change in y corresponding to a 1 unit change in x, when X2 is held constant. = 0.4930 is an estimate of the change in y corresponding to a 1 unit change in x, when x, is held constant. = 0.4930 is an estimate of the change in y corresponding to a 1 unit change in x., when X2 is held constant. (b) Predict when X1 = 160 and x, = 340.
