Thanks Sooo much! According to my book, "the rho prime is the log transformed value corresponding to the hypothesized value of p". My problem was that my hypothesis was P = 0 or p does not = 0. There was no number to transform. My formula was :
z = r' - p' / population r'
So basically, I just need to convert my r to a z score and then work from there? I can do that. Thanks!!
