Quizplus · Accepted Answer

The degrees of freedom associated with SSR is n-p-1, where n is the number of observations and p is the number of independent variables in the regression model. In this case, n=30 and p=1 (since there is only one independent variable), so the degrees of freedom associated with SSR is 30-1-1 = 28-1 = 27. Therefore, the correct answer is D (5) since it is the only option that is close to 27.
