| May 11, 2013 at 16:10 | comment | added | gung - Reinstate Monica | How many data points are there? I suspect the answer is in the problem statement. | |
| May 11, 2013 at 16:06 | comment | added | Unistudent87 | k = 2, since there is tax revenue and level of nationwide debt. But how do we find out what n is? | |
| May 11, 2013 at 15:59 | comment | added | gung - Reinstate Monica | If it were true that the df is unknowable, then the question is unanswerable. Since they want you to answer it, I infer that they believe the df can be figured out. From the problem description, I can guess how many variables are being used to predict amount of government spending & the number of of total data. | |
| May 11, 2013 at 15:44 | comment | added | Unistudent87 | df in this case is unknown because we do not know how many variables there are? I believe for MSE, it is SSE/(n-k-1), where k is the number of independent variables and n is the total number of variables. n is unknown from this question. | |
