one way is:
1. convert sample r to Fisher's BIG Z (consult conversion table)
2. find standard error of Fisher's Z ... (find formula in good stat book)
3. for 95% CI ... go 1.96 standard error (from #2) units on either side of
Z (from #1)
4. convert EACH end of the CI in Fisher Z units back to r values (use table
from #1 in reverse)
