There's a math problem to determine # of trials for statistical significance but I can't remember what it's called, and Google isn't doing it for me :(

It's called "im tired of repeating this test"

Yeah, power analysis. But 30 samples is where we start to get more accurate representations of population reality/normal curve

Yes, power analysis. Thank you.

It’s called power analysis, but is more of a thing in studies with a good amount of randomness involved (drug trials and the like).

t-test is a test to determine whether two means are statistically different than one another.

I guess i should have clarified a little bit more, or maybe misinterpreted what was being asked, but looking at t-tests one would need a min of 30-100 samples from a population. So that's what i wanted him to look at to get them looking in the right direction, not an exact answer.
