18. Consider the following diagnostic problems for a group of fictional diseases:

a. A patient is presenting symptoms and history suggest a diagnosis of globoma, with about .8 probability. If it isn´t globoma, it’s either popitis of flapemia. Each disease has its own treatment, wich is ineffective against the other two diseases. A test called the ET scan would certainty yield a positive result if the patient had popitis, and a negative result if she has flapemia. If the patient has globoma, a positive and a negative result are equally likely. If the ET scan was the only test you could do, should you do it?. Why or why not?.

b. A different patient has a .8 probability of umphitis. A positive Z ray result would confirm the diagnosis, but a negative result would be inconclusive; if the result is negative, the probability would drop to .6. The treatment for umphitis is unpleasant, and you feel it is just as bad to give the treatment to a patient without the disease as to let a patient with the disease go untreated. If the Z ray were the only test you could do, should you do it?. Why or why not?.

Explain your way of make the predictions …
