Haijie,

It seems as if you are working on a power question that is embedded in
another concern, a concern which I don't quite understand. It seems to me
that you can get the sample size required for a t-test with a given effect
size from any of the many power calculators on the web. So suppose you knew
that a sample of 346 was required to given a power of xx for an effect size
of yy, would that answer your questions?
