Buatlah 99% confidence interval
WebQ2: A 99% confidence interval is wider than a 95%, all else being equal. Therefore, it's more likely that it will contain the true value. See the distinction above between precise and accurate. If I make a confidence interval narrower with lower variability and higher sample size it becomes more precise because the values cover a smaller range.

WebTranscript. If we want to be 95% confident, we need to build a confidence interval that extends about 2 standard errors above and below our estimate.
