Trying to understand how to solve #2 and #4. I know how to find the standard deviation of p-hat but I am uncertain about the 95% confidence interval. I tried to do the formula for the standard deviation but then number 4 uses a different interval and I found that I wasn't using 95% for my answer to number 2. What am I missing?
