In the 1960 presidential election, 34,226,731 people voted for Kennedy; 34,108,157 for Nixon, and 197,029 for third-party candidates. Would it be appropriate to find a confidence interval for the proportion of voters choosing Kennedy

Answer:

Yes, it would be appropriate to find a confidence interval for the proportion of voters choosing Kennedy since we have the necessary information (number of people who voted for Kennedy, number of people who voted for Nixon, and number of third-party votes) and the sample size (total number of voters) is large enough to assume a normal distribution. A confidence interval can provide an estimate of the true proportion of voters who chose Kennedy and the level of uncertainty around that estimate.
