**MathGuru**, Monday, August 11, 2008 at 9:37pmSince you are already given the values for the confidence interval, take those values, add them together and divide by 2. This will be the proportion of the sample used to generate the interval. A 90% interval means that you can be 90% sure that the population proportion is contained within that interval.
