Negative test | Mathematics homework help
A genetic condition is found that affects 10% of adults in the US population. In a city with 100,000, that means that approximately 10,000 people have the condition, and 90,000 people do not. Fortunately, there is a genetic test for the gene that causes the disease. The test has an error rate of 1%.
Of the people who have the condition, 1% of them will have false negatives. If false positives also occur at the rate of 1% then about 1% of the 90,000 who do not have the bad gene will test positive.
