This brief video from NPR  (they make videos, what?) describes how the CDC will be randomly sampling Atlanta residents to test for COVID-19 antibodies. The efforts hope to provide a better estimate of the spread of the disease. H/t to Sy Islam  for sharing this with me.   I think you could use this in class as a super-fast example of how we use samples to generalize about larger populations.     The CDC is sending out employees to conduct antibody tests on a random sample of Atlanta residents. The tests are meant to show how many people have been infected with the coronavirus. pic.twitter.com/mXqznHUJmV   — NPR (@NPR) April 29, 2020
