Suppose that 2% of a population carries antibodies to a virus. For a research project, you need 8 people with antibodies to the virus. How many people must you test to be 95% certain of getting at least 8 people with the antibodies? This problem will need some trial and error...you are trying to find n so that P(X > 8) = 0.95.
