find the true positive.

Can someone please teach me how to go about this question and how to set it up, please?

I think the true positive is 96%. Is that correct? For future reference, can someone please teach me how to find the true negative, false negative, and false positive as well?

Answer 1

True positive = .0278 * .96 = ?

False positive = .0278 * .04 = ?

True negative = (1-.0278) * .96 = ?

False negative = (1-.0278) * .04 = ?
