A 95 percent confidence interval includes all the means we would expect to obtain 95 percent of the time when repeatedly sampling from a population. This interval gives us a range of values within which we can be 95% confident that the true population mean lies, assuming the sampling distribution is normal or the sample size is large enough for the Central Limit Theorem to apply.
