Agroup of researchers wants to be able to detect those who have contracted the zombie virus before they turn into zombies. those who test positive will be quarantined for two weeks. if they show no signs of being a zombie, they will be freed. they have developed a simple test where they swab the person’s ear (mouth would be too dangerous).
they gathered 200 people of which 50 were known to be have the zombie virus.
of those who had the virus, 48 tested positive. of those who did not have the virus, 135 tested negative.
based on the data presented above, do you think the test for zombieism is effective at detecting future zombies. why or why not?
