Lupus is a medical phenomenon where antibodies that are supposed to attack foreign cells to prevent infections instead see plasma proteins as foreign bodies, leading to a high risk of blood clotting. It is believed that 2% of the population suffer from this disease. The test is 98% accurate if a person actually has the disease. The test is 74% accurate if a person does not have the disease.

If an individual tests positive for lupus, what is the probability that this is a false positive? (In other words, what is the probability of an individual not having lupus, given that they received a positive test result?)

Do not give your answer as a percentage chance, but rather as a decimal probability (i.e., 0.xxx).

Answer: the answer should be lower than because this is the percentage of people who get diagnosed with a disease that is not lupus 0.465 so about 50% or 0.5 hopefully that help I don't know the answer for the amount of people who don't have it and get misdiagnosed there is no information on it based on what I've seen

Step-by-step explanation: Its based on a study from the Lupus Foundation of America
