How many authors wrote the Old and New Testament? I know how many people wrote the Bible, that is, around 40. But what percent of that is Old Testament and what percent is New?

Note: I know I could spend half an hour looking through the lists to split them up but 1. Since this is not quickly answered anywhere, let's make it easier for people who want to know, and 2. Maybe someone here will know off the top of their head.
I think it’s like this: 32 Old Testament and 8 New Testament
