Chapter 6, Problem 6.15P

Two individuals are running for mayor of your town. 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. (HINT: 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 [ $\alpha =0.01$]in the confidence interval, it may be anywhere in the interval.)

$\begin{array}{l}{P}_s=0.51\\ N=578\end{array}$
