## Main Question or Discussion Point

hi. i have two samples with known mean and variance. do you know which test i use to determine the confidence that they are drawn from different populations?

also if you know a link that explains how to calculate the test that would be helpful. i have some stats books too in case needed. (but couldn't seem to pick out which the right test was)

thanks,

gt
