    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?

    Can u please explain why you picked 110 instead of 109? where does the result show this detail??

    • @joshemman
      @joshemman  2 месяца назад

      You always round up to the next integer. Whether it is 109.8 or 109.1, you round up to 110. It means a sample of size 109 is not enough to achieve that error limit; you need an additional unit.
