A CNN poll conducted by SSRS in November 2023 surveyed a random sample of 1,795 U.S. households. They were asked the following question: "How worried are you, if at all, about the risk of climate change in the community where you live?" Of those surveyed, 63% said they were either very or somewhat worried. The poll reported a margin of error of 3.2% (this is the margin of error associated with a 95% confidence interval).The population of interest is the 1,795 U.S. households surveyed If researchers wanted to cut the margin of error in half, they would need to survey twice as many U.S. households
