TABLE 14-6
One of the most common questions of prospective house buyers pertains to the cost of heating in dollars (Y).To provide its customers with information on that matter,a large real estate firm used the following 2 variables to predict heating costs: the daily minimum outside temperature in degrees of Fahrenheit (X₁)and the amount of insulation in inches (X₂).Given below is EXCEL output of the regression model. Also SSR (X₁ ∣ X₂)= 8343.3572 and SSR (X₂ ∣ X₁)= 4199.2672
-Referring to Table 14-6,the value of the partial F test statistic is ________ for
H₀ : Variable X₂does not significantly improve the model after variable X₁ has been included
H₁: Variable X₂ significantly improves the model after variable X₁ has been included
