Confidence interval for proportion of internet users


An organization polled 816 internet users, asking whether they have logged onto the internet using a wireless device or not. 259 responded "yes"

Find a 98% confidence interval for the proportion of internet users who have used a wireless device. If only the success/failure condition is not satisfied, then instead construct an adjusted 98% confidence interval using the pseudo observation method.

What is the 98% confidence interval?
