Question: Lowering the drinking age. A July 2007 Gallup Poll asked a random sample of 464 adults whether they would favor or oppose a federal law that would lower the drinking age in all states to 18. Among the respondents, 357 said they would oppose such a law. We can act as if the sample were an SRS. Give a 95% confidence interval for the proportion of all adults who would oppose a federal law that would lower the drinking age in all states to 18.
