6. [-/2.77 Points] DETAILS ASWSBE14 15.E.001. y 1 . y when The estimated regression equation for a model involving two independent variables and 10 observations follows. ý = 21.1670 + 0.5809x + +0.4950x2 (a) Interpret b, in this estimated regression equation. Ob = 0.5809 is an estimate of the change in y corresponding to a 1 unit change in x, when x, is held constant. Ob = 0.4950 is an estimate of the change in y corresponding to a 1 unit change in xz when x, is held constant. Ob = 0.4950 is an estimate of the change in y corresponding to a 1 unit change in x, when x, is held constant. Ob = 21.1670 is an estimate of the change in y corresponding to a 1 unit change in nx *2 is held constant Ob = 0.5809 is an estimate of the change in y corresponding to a 1 unit change in x2 Interpret b, in this estimated regression equation. b2 = 0.4950 is an estimate of the change in y corresponding to a 1 unit change in x, when xy is held constant. = 0.5809 is an estimate of the change in y corresponding to a 1 unit change in x, when xis held constant. Oь, = 0.4950 is an estimate of the change in y corresponding to a 1 unit change in x, when x is held constant. Ob2 = 21.1670 is an estimate of the change in y corresponding to a 1 unit change in x, when x, is held constant. Ob2 = 0.5809 is an estimate of the change in y corresponding to a 1 unit change in x, when xis held constant. when x is held constant. y = (b) Predict y when x1 = 190 and x2 = 330.
