1) Suppose that 2% of a population is infected with a virus. You test a random sample of 1000 members of this population. How many of the people in the sample would you expect to have the virus? Round to one decimal if needed.

2) Suppose that 10% of a population carries antibodies to a virus. For a research project, you need 28 people with antibodies to the virus. How many people should you test so that the expected number of people with the antibodies is 28? Round up to a whole number.
