The critical value for a two-tailed F -test is 2.65, when $a = 0.05$ , the sample size from which the variance
for the numerator was obtained = 10, and the sample size from which the variance for the denominator
was obtained = 15.

The critical value for an F-test depends on the degrees of freedom for the numerator and denominator, which are $df_1 = 9$ and $df_2 = 14$ respectively. The critical value for these degrees of freedom at $a = 0.05$ is not 2.65.
