Consider the town of Springfield, where there are 100,000 adults. Consider a different genetic disease, which affects only 0.1% of the U.S. population. The test for this disease is also 98% accurate. All the adults in Springfield were also tested for this disease.

1. How many of the residents of Springfield are likely to have the disease?
2. How many of the people who actually have the disease get a positive test result?
3. How many of the people who do not have the disease get a positive test result?
4. Of the people who get a positive test result, how many of them have the disease? Convert this to a percentage: What percent of people who get a positive result actually have the disease?
