I have to calculate mean and standard deviation of sample means of size 30 (with replacement) from a population of size 87. Its impossible to do it without the help of any software because N^n is 87^30.

I tried to get this distribution by using SPSS but it only generates random samples and not all the samples of size 30. I also could not find anything in Megastat.

Any help in this regard will be highly appreciated.
