To find the confidince interval first you must find meu (average) and the standerd divation ( the square root of n*p*(1-p)). To find 95% interval times the standerd divation by 1.96 and add and minus it from the average. The margen of error is what you add or minus from the average to get the 95% interval. To find the percent margen of error just find the pecent with with the margen of error.
