How does this sampling variation affect their estimate of 4.4%? In other words, what would be a plausible range of values for this difference that accounts for this sampling variation? We can answer this question with confidence intervals! Furthermore, since the Mythbusters only have a single two-sample of 50 participants, they would have to construct a 95% confidence interval for \(p_{seed} - p_{control}\) using bootstrap resampling with replacement.
