The range of values within which the population mean is expected to fall is called the confidence interval about the mean. This interval gives a measure of the precision of the sample statistic (like the mean) in estimating the population parameter (like the population mean). The level of confidence is typically set at 95% or 99%, and the interval is based on the sample size, the sample statistic, and the standard error of the mean. Larger sample sizes and smaller standard errors result in narrower confidence intervals.
