Question 1125833: Suppose a test for a disease has a sensitivity of 95% and a specificity of 60%. Further suppose that in a certain country with a population of 1,000,000, 20% of the population has the disease.

Disease + Disease - Total
Test + 190000 320000 510000
Test - 10000 480000 490000
Total 200000 800000 1000000
Sensitivity is testing positive when one has the disease
Specificity is testing negative when one doesn't have the disease
