Suppose that we wish to know with 91% confidence the percent of the electorate in a county that identifies itself as Democratic. We conduct a simple random sample of 800 people in this county and find that 424 of them identify as a Democrat. Find the 91% confidence interval for the true proportion. Round answers to 2 decimal places where possible. (a) Number of successes x= (b) n = (c) Probability of success p'= (Use decimal format)
