Chapter 9.4, Problem 1E

Predicting y-Values In Exercises 1−4, use the multiple regression equation to predict the y-values for the values of the independent variables.

1. Cauliflower Yield The equation used to predict the annual cauliflower yield (in pounds per acre) is

ŷ = 24,791 + 4.508x₁ − 4.723x₂

where x₁ is the number of acres planted and x₂ is the number of acres harvested.

(a) x₁ = 36,500, x₂ = 36,100

(b) x₁ = 38,100, x₂ = 37,800

(c) x₁ = 39,000, x₂, = 38,800

(d) x₁ = 42,200, x₂ = 42.100
