Enter negative values as negative numbers, if necessary. a. Develop an estimated regression equatin relating y to axi y = Predict y if xi = 45. y = b. Develop an estimated regression equation relating y to a2 Predict y if 2 = 15 c. Develop an estimated regression equation relating y to x1 and x2. y = Predict y if x1 = 45 and æ2 = 15

Answer 1

a. Regression equation relating y ton, - 9 = .6 + 1 gs, Pridict yif 21,= 45 y = 132.35 y to ar, Regression equation relating 9 = 135 +0.286 m2 predict y if x = 15 y = 139.29 to a $ 212 Regression equation relating 4 = 4S. 2 + 1972 - 0 - 0 732, pocdict y if m= 45 x2=15. 4 = 132.7G.
