    Testing two variances is the same as testing two means?

    That is false right because you use the f-test for variances and t-test for means...?

    You use different tests because the statistics in question have different
    distributions. It is the difference in distributions which significant.

    (note in both cases F and t we are assuming normality of the underlying
    distributions from which the samples are taken).
