Calculate Quantile
In a recent poll before an election, 1000 voters were surveyed randomly. 520 of them stated they would vote for the incumbent mayor.
Calculate the sample proportion \(\hat{p}\) of voters supporting the mayor.
Construct a \(95\pourcent\) confidence interval for the true proportion of voters who support the mayor.
