... The Sampling Distribution of p̂ We construct interval estimates for p in much the same way as our confidence intervals for a mean. We can calculate p̂ and use it as the center of our interval and then add a margin of error above and below p̂ . The experiment of drawing a sample of n objects and cou ...
