Suppose a certain virus (sorry!) affects 0.3% of the population. A test used to detect the virus is positive 88% of the time if the person has the virus (true positive) and 10% of the time if the person does not have the virus (false positive). Fill out the rest of the table and use it to answer the questions based on a total sample of 100,000 people. Virus No Virus Total Positive Test Negative Test Total 100,000 a) Find the probability that a person has the virus given that they have tested positive. Give your answer as a percent rounded to two places after the decimal. Don't enter the % symbol. b) Find the probability that a person does not have the virus given that they test negative. Give your answer as a percent rounded to two places after the decimal. Don't enter the % symbol.
