1. For a certain disease, a new test is proposed based on the occurrence of a specific protein X in the blood of patiets. In other words, this test gives a positive result if the protein X is found in the blood of the tested individual. According to this new test performed in a subpopulation composed of healthy people and people with this disease, it was reported that among the patients with this disease, there were 95% who had the protein X. On the other hand, the protein X was present only in 30% among the healthy subgroup. The general incidence of this disease among the population is known to be 10 percent, which is determined from various surveys over the years. From this data, derive a probabilistic measure to determine the accuracy of this test. Please briefly comment on your results.
