Suppose that the manufacturer of a home-based rapid antigen COVID test claims to be 90% accurate. Data indicates that about 10% of residents in a certain county have COVID. 1. Fill in the table with the expected results for 1,000 residents taking this test. Round each to the nearest whole number. Has COVID | Does NOT Total have COVID Test positive for COVID Test negative for COVID Total 2. What percentage of residents will test positive? 3. Of those who actually have COVID, how many would we expect to test negative? Explain the significance of this result.
