    Hi! can anyone help me regarding the confidence interval?

    Hi,
    Can anyone help me with the following question?


    The polling agency has randomly asked 100 potential voters. Of those, 55 have responded that they will vote for Mr. Obama.
    Should Mr. Obama feel confident about the re-election based on this result?
    Using a 90% confidence interval, estimate the true percentage of voters who will vote for Mr. Obama.



    Many thanks

    I think that these pollers are a bit premature... Four years premature...
