A rule of thumb is that if the ratio of the larger to smaller standard deviation is greater than two, then the unequal variance test should be used. With a computer one can easily do both the equal and unequal variance t test and see if the answers differ. Now, if we go back to one of the steps in the t-test, we see that we calculate: In this step we add the separate values of s 2 /n for each mean.
