   Question

   Two nested models are compared. Reduced model: $\hat{y} = a+b_{1}x_{1}+b_{2}x_{2}+b_{3}x_{3}$. Complete model: $\hat{y} = a+b_{1}x_{1}+b_{2}x_{2}+b_{3}x_{3}+b_{4}x_{1}x_{2}+b_{5}x_{1}x_{3}$. The sample size is 160. How many degrees of freedom are in the numerator of the Model Comparison Test?
