Fantastic bro! subbing. Great format. Only thing could be to show it on the ti84 as well but I don't even know if that is something that can be done.
Thanks

So when population variability (sigma) is unknown use sample sigma instead denoted by (s) as n = (Z_sub{a/2} x SE)^2/E^2 where SEM stands for sample error of mean. Am I right?
