I have computed a mean correlation as the back-transformation of the
mean of the Fisher Z transformations of a number of Pearson
correlations.
1. Can I test the difference of the mean correlation from a population
correlation of zero?
2. If so, do I use the sampling distribution of the Pearson
correlation?
3. Also, do the degrees of freedom for a significance test of the mean
of k correlations = N - 2k?
