The equation used to predict annual cauliflower yield (in pounds per acre) is y = 23,419 +4.506x, -4.655x2, where x, is the number of acres planted and X, is the number of acres harvested. Use the multiple regression equation to predict the y-values for the values of the independent variables. (a) x, =36,700, x2 = 37,000 (b) x, = 38,300, x2 = 38,600 (c) x, = 39,300, x, = 39,500 (d) x, =42,600, X2 =42,700 (a) The predicted yield is pounds per acre. (Round to one decimal place as needed.) (b) The predicted yield is pounds per acre. (Round to one decimal place as needed.) (c) The predicted yield is pounds per acre. (Round to one decimal place as needed.) (d) The predicted yield is pounds per acre. (Round to one decimal place as needed.)
