I am pretty confused taking minitab t test or z test
as in a post , Dason said that n=30 for determining t test or z test is lame, now I have to calculate CI in minitab, and my sample size is 24, and I am totally confused whether to use t test or not..
since I tried z test and t test as well..and answer is different.
any help?
