Complete the table below.  Suppose 6% of those who take the COVID-19 test actually have the virus. The test is 90% accurate in identifying those with COVID-19 and those without COVID-19. Out of 1000 people tested, find out how many people will test positive and how many of those are “false positives” (those who test positive but don’t actually have the virus).  Tested Positive Tested Negative Total Actually with COVID-19 [a] [b] 60 Actually without COVID-19 [c] [d] 940 Total [e] [f] 1000 Copy this table on your paper and fill in the blank boxes. Write ONLY your answers in the response box. Show your work which justifies your answers ON YOUR PAPER.
