Explanation / Answer

The confidence interval represents the precision with which weare able to report the effect size, and the larger the sample, themore precise the estimate. As a practical matter, sample size isoften the dominant factor in determining the precision of theconfidence interval. Let's say you have a 100(1-)% confidence interval, where is the confidence interval. There's a 100(1-)%probability that the "true" mean is within the confidence interval,and 100% that it's not. Example: Your confidence level = 0.05, which impliesyou have a 95% confidence interval for the population mean. Inother words, there's a 95% probability that the "true" populationmean is within the confidence interval, or there's a 5% ()that the "true mean is not within the confidence inteval.
