The 95 percent confidence interval indicates the range within which the true mean probably lies. It is a measure of the level of uncertainty or degree of confidence associated with the results of a study. A 95% confidence interval means that if we repeat this experiment many times with different samples, we would expect the true mean to fall within this range about 95% of the time.
