Answer #1

Let d1 and d2 denote the degrees of freedom for an F- test.

The degrees of freedom (DF) are the amount of information your data provide that you can "spend" to estimate the values of unknown population parameters, and calculate the variability of these estimates. This value is determined by the number of observations in your sample.

d1 and d2 are functions of no. Of independent variable.and total no. Of points in the data i.e number of data sets.

So, the answer is E. Both A and C above.
