that afflicts 20% of the population. There is a test for this condition, and the reliability st can be characterized as follows: • false-positive rate 10%-for those who do not have the condition, 10% will st positive. false-negative rate = 5% – for those who have the condition, 5% will test neg- ative. f you receive a positive test result, what is the likelihood that you have the condition?

Question
This question asks you to extend the medical-test example from class. Suppose there is a medical condition that afflicts 20% of the population. There is a test for this condition, and the reliability of this test can be characterized as follows: false-positive rate = 10%- for those who do not have the condition, 10% will test positive. • false-negative rate 5%- for those who have the condition, 5% will test neg- %3D ative, (a) If you receive a positive test result, what is the likelihood that you have the condition? If you receive a negative test result, what is the likelihood that you do not have the condition? (b) Repeat part (a), except now assume that the false-positive rate is 5% and the false-negative rate is 10%,
