Dear ElMaestro,

Thank you for your input! Since I'm still a long way from learning R coding, I was able to find the correct Excel function Ft(x,DF) from an add-in from EasyfitXL, which is the =StudentCdf. With this I was finally able to replicate Potvin's Example#2 Method B. Optimal n was achieved by tabulating 20 incrementing n's, and using a lookup function to find the lowest >80% power. I admit this method is crude, but for our current purpose, it will probably do.

Best regards,

Abel.

if only they could discover enough facts about a problem,
these facts would somehow arrange themselves
in a compelling and true solution.    Theodosius Dobzhansky
