Two individuals are running for mayor of Shinbone, Kansas. You conduct an election survey a week before the election and find that 51% of the respondents prefer candidate A. Can you predict a winner? Use the 99% level. (In a two-candidate race, what percentage of the vote would the winner need? Does the confidence interval indicate that candidate A has a sure margin of victory? Remember that while the population parameter is probably (a 5 .01) in the confidence interval, it may be anywhere in the interval.)
