Obi The estimated regression equation for a model involving two independent variables and 10 observations follows. 9 = 24.1270+ 0.5604x4 + 0.4990x2 (a) Interpret b, in this estimated regression equation. -0.5604 is an estimate of the change in y corresponding to a 1 unit change in xy when X, is held constant. OD, -0.4990 is an estimate of the change in y corresponding to a 1 unit change in xy when X, is held constant. Ob- = 24.1270 is an estimate of the change in y corresponding to a 1 unit change in X, when X2 is held constant. ob, -0.5604 is an estimate of the change in y corresponding to a 1 unit change in x, when X, Is held constant. 061 -0.4990 is an estimate of the change in y corresponding to a 1 unit change in xwhen X, is held constant. Interpret by in this estimated regression equation. O b2 - 0.5604 is an estimate of the change in y corresponding to a 1 unit change in x, when X, is held constant O 02 - 24.1270 is an estimate of the change in y corresponding to a 1 unit change in x, when X, is held constant. O 02-0.4990 is an estimate of the change in y corresponding to a 1 unit change in X, when O by = 0.4990 is an estimate of the change in y corresponding to a 1 unit change inx, when X, is held constant. O B2 - 0.5604 is an estimate of the change in y corresponding to a 1 unit change in xy when X, is held constant. is held constant. (b) Predict y when X1 - 170 and X2 - 310
