Not sure whether a Fisher's z transform is appropriate here. For H 0: ρ = 0 (NB: null hypothesis is for population ρ, not sample r ), the sampling distribution of the correlation coefficient is already symmetric, so no need to reduce skewness, which is what Fisher's z aims to do, and you can use Student's t approximation.
