In a survey of520potential jurors, one study found that350were regular watchers of at least one crime-scene forensics television series.(a) Assuming that it is reasonable to regard this sample of520potential jurors as representative of potential jurors in the United States, use the given information to construct a 95% confidence interval for the true proportion of potential jurors who regularly watch at least one crime-scene investigation series. (Use Table 3 inAppendix A. Give the answer to three decimal places.)
