Question

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 0.04 of the population suffer from this disease. The test is 0.97 accurate if a person actually has the disease. The test is 0.74 accurate if a person does not have the disease. There is a line from the Fox television show "House" that is often used after a patient tests positive for lupus: "It's never lupus." Do you think there is truth to this statement? Use appropriate probabilities to answer.
