Please help me with this problem.
The sensitivity of a test is the probability that a person having the disease will test positive; the specificity of a test is the probability that a person not having the disease will have a negative test.
Experience indicates that its sensitivity is .0934 and that its specificity is 0.968. Furthermore, it is know that roughly 1 in 500 people has the disease.
Determine the probability that a person testing positive actually has the disease.
