Let P(X=x) be the probability that a random variable equals a specific
measured numerical value, x.
Let p(x) denote the probability mass function of that random variable,

We want to do a hypothesis test on the difference between two
population means and we do not know the population variances. We
do a test of hypothesis on the equality of variances and determine that
we have evidence that the variances, though unknown, are equal. How
many degrees of freedom will our test statistic have?
