THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
The model y = β₀ + β₁X₁ + β₂X₂ + ε was fitted to a sample of 25 families in order to explain household milk consumption: where y = Milk consumption,in quarts,per week,x₁ = Weekly income,in hundreds of dollars,and x₂ = Family size.The least squares estimates of the regression parameters were b₀ = -0.03,b₁ = 0.05,and b₂ = 1.1,with coefficient standard errors
= 0.02;
= 0.38.The total sum of squares and the error sum of squares were found to be 165.8 and 66.32 respectively.
-Test against the appropriate one-sided alternative,the null hypothesis that,for fixed family size,milk consumption does not depend linearly on income.Use α = 0.025.
