A large city will hold an election for mayor in two weeks. There are only two candidates, Adam and Ashley. Last night, a sample of 400 voters was selected, 262 of which stated that they intend to vote for Adam. Let p denote the overall proportion of voters in the city that intend to vote for Adam.

Looking at the information in this sample, what would the value of the sample proportion, p of voters that intend to vote for Adam be? What would the 95% confidence interval for p be, and what is the margin of error for the confidence interval?
