A newsgroup is interested in constructing a 95% confidence interval for the proportion of all Americans who are in favor of a new Green initiative. Of the 602 randomly selected Americans surveyed, 366 were in favor of the initiative. Round answers to 4 decimal places where possible. a. With 95% confidence the proportion of all Americans who favor the new Green initiative is between and b. If many groups of 602 randomly selected Americans were surveyed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population proportion of Americans who favor the Green initiative and about percent will not contain the true population proportion.

The second annual Airplane Etiquette Study commissioned by Expedia asked 1000 Americans to rank the most annoying on-board behaviors of fellow passengers. Rear seat kickers topped the list with 67% of those surveyed ranking this annoying behavior as number one. You create a 99% confidence interval and find the population proportion to be within 0.038 of 0.67, or between (0.632, 0.708).
