SCENARIO 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 ( X ₂ ). Given below is EXCEL output of the regression model.

-Referring to Scenario 14-6,the partial F test for
H₀ : Variable X₂ does not significantly improve the model after variable X₁ has been included
H₁ : Variable X₂ significantly improves the model after variable X₁ has been included has _____ and _____ degrees of freedom.
