When df are in the denominator,
A) The sample variance becomes an unbiased estimator of the population variance.
B) The number of degrees of freedom associated with the sample variance is n - 1.
C) The sample variance can be calculated by dividing the sum of squares by the degrees of freedom.
Thus, all of the statements are true, and the correct answer is D.
