Use the following information to answer the question(s) below.

Delmarva Power is a utility company that would like to predict the monthly heating bill for a household in Kent County during the month of January. A random sample of 18 households in the county were selected and their January heating bill recorded. This data is shown in the table below along with the square footage of the house (SF), the age of the heating system in years (Age,) and the type of heating system (heat pump = 1 or natural gas = 0).



Conduct the hypothesis test, showing the calculations, to test the significance of the overall regression model for predicting a heating bill using α = 0.05.

Because = 13.94 is greater than Fα = 3.344, we reject H0 and conclude that at least one of the population coefficients for our independent variables is not equal to zero. In other words, you can use this regression model to predict the monthly heating bill for a household based on the square footage of the house (SF), the age of the heating system in years (Age), and the type of heating system (heat pump or natural gas).
