Assume that you work in the examination oce for one of the state's biggest medical coverage organizations. Your rst task is to contemplate the expense eectiveness of organizing a general test for a sickness called SOS. Your rm is considering making the test free and general for each of the 10 million of its customers in Texas. The actual tests are a signicant cost. However whenever got ahead of schedule, before the beginning of its most noticeably awful manifestations, SOS can be dealt with substantially more expense eectively. This might actually save your rm a lot of cash as it were. You are accused of understanding the properties of the test. We realize that SOS aicts approximately 1 Texan out of each 1000, and we should additionally accept that your 10 million customers are an agent test, everything being equal (so you can anticipate that this base rate for Texas should hold for your customers also). No clinical trial is awesome, however this one is sensibly exact: it gives a positive outcome for 95% of individuals who have SOS, and a pessimistic outcome for 99% of individuals who don't have SOS.
