In an exit poll for a given state, consisting of 625 randomly sampled voters, 328 say they voted for Obama. Is there sufficient evidence for you to conclude that Obama recieved a majority of the votes in this state, with a probability of type I error no more than 1%?

I would love for help on this problem. I missed two days of class (for personal reasons), and I do not have the new notes on type I errors. So I would love it if someone could work this example problem for me and explain a little so I know what to do for the homework.

Thanks in advance!!!
