P value in a rank-biserial correlation

[Mark Lee]

Hello, can someone tell me how to compute the p value in a rank-biserial correlation?

I understand the rank-biserial correlation coefficient is a function of the Mann–Whitney U test, but am not sure how to derive the p value when doing rank-biserial correlations.

Many thanks in advance for any guidance!

Kind regards,
