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 ( X<sub>1</sub> ) and the amount of insulation in inches ( X <sub>2</sub> ). Given below is EXCEL output of the regression model. Also SSR (X<sub>1</sub> | X<sub>2</sub>) = 8343.3572 and SSR (X<sub>2</sub> | X<sub>1</sub>) = 4199.2672 -Referring to Scenario 14-6,the value of the partial F test statistic is _____ for H<sub>0</sub> : Variable X<sub>2</sub> does not significantly improve the model after variable X<sub>1</sub> has been included H<sub>1</sub> : Variable X<sub>2</sub> significantly improves the model after variable X<sub>1</sub> has been included
