The degrees of freedom for the numerator of the F ratio can be calculated to be 9.

<h3>How many degrees of freedom is the numerator of the F ratio?</h3>

The degrees of freedom for the numerator can be found to be:

= number of exams graded - 1

Solving gives:

= 10 - 1

= 9

In conclusion, the degrees of freedom for the numerator of the F ratio is 9.
