You can't take a random selection of 1300 out of a (possibly non-representative) 25,000 and have the results be valid.

Well obviously if the 25,000 is not representative, the results will not be statistically significant. Duh.
But you can certainly take a random sample of 1,300 our of a representative population and get valid results. Stats 101.
