In the search for a cure for the Coronavirus, it is important to determine what proportion of the population has antibodies, which would likely make them immune or less susceptible to the effects of the disease. According to an article in Politico published on April 26, 2022, 60% of Americans currently have detectible antibodies for Covid-19. A researcher thinks that more than 60% of Americans currently have antibodies for Covid-19. Suppose that the researcher takes a simple random sample of 1200 Americans, tests their blood, and find that 750 of them have antibodies. Use a 0.05 significance level to test the researcher’s claim.
