OK. You have a case where you sample from a 'population' of times from situation A a
number of times, and from Situation B a number of times. Maybe C, D, etc. too.
To compare 2 of these babies, use a t test. Keep sample size (n's of each) about
equal, and go for it. Student 't' test is
the real question is, 'how much accuracy (precision, variance) is
suitable?'
If you were to repeat the simulation run (i.e., a test) a total of n
times, then you could say that the true mean elapsed time was x-bar +/-
(certain amount), with say 95% confidence.
That is, if you were to then
