Gastwirth estimated that, if the person is actually infected with HIV, this test produces a positive result97.7% of the time. If a person is not infected with Hiv the test result is negative 92.6% of the time.According the US Centers for Disease Control (CDC) 0 34% of Americans were infected with HIV in 2015.(1). What is the probability that a randomly selected person tests positive for the ELISA test?(11). What is the probability that a randomly selected person whose ELISA test is positive actually isinfected with HIV?(11). Are events {a person tests positive for the ELISA test} and {a person is infected with HIV}independent? Explain.(iv). Is the ELISA test effective in detecting who is infected with HIV? Is it effective in detecting who is notinfected with HIV? Explain.

Given information: P(positive| infected with HIV)=97.7%=0.977 P(negative| not infected with…
