A survey of 1000 adults in the US conducted in June 2016 asked "Do you think that fines for smoking out of special zones are too large?" The proportion of respondents in favor of making the fines smaller was 23%. Find a 90% confidence interval for the proportion of US adults favoring the fines to be smaller. What is the margin of error? If we want a margin of error of only 1% (with 95% confidence), what sample size is needed? Select answer from the options below The confidence interval is (0.218, 0.242). The margin of error is 1.2%. Sample size should be 4793. The confidence interval is (0.208, 0.252). The margin of error is 2.2%. Sample size should be 4793. The confidence interval is (0.218, 0.242).
