How to perform two samples z test in Doronix Math Toolbox?

I'm using Doronix Math Toolbox. But I can't find how to perform 2 samples z test there. Can anyone help me?

Thank you very much.

Well if you're interested in if the samples are different and you're saying that you aren't sure if they have the same mean/sd as the population then just use the two sample t-test. It sounds like you want to choose the "Independent samples T test" in your menu.
