**PsyDAG**, Tuesday, July 27, 2010 at 11:07amI assume "SY" is your abbreviation for standard deviation (SD).

Z = (mean1 - mean2)/standard error (SE) of difference between means

SEdiff = √(SEmean1^2 + SEmean2^2)

SEm = SD/√(n-1)

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to the Z score.

I'll let you do the calculations.
