so sorry, I have never used this I will type in exactly what I have Regarding the Elias Test for HIV. Assume the test returns a positive result for 99.8% of those with the HIV virus and that when the test is given to those not infected it returns a positive result 1.5% of the time. Heterosexuals without specific risk factors for HIV have an infection rate of about .02%. What is the probability that a random person in this group would test positive?
anybody got this?
This is a conditional probability, you have to use bayes formula, also draw a tree diagram to make sense of the probabilities and its compliments
not sure I know what you are talking about?
I will have to check in later
use Bayes formula of reverse probability ans will be 196/15193
