When testing for the difference between 2 population variances with unequal sample sizes, the number of degrees of freedom is given by (n1-1) and (n2-1), where n1 is the sample size with the larger variance. Therefore, in this case, the number of degrees of freedom are 7 and 9 for n₁ = 8 and n₂ = 10, respectively.
