Confidence interval is defined as a range of values that probably contains the population value. It is used to estimate the population parameter (such as mean or proportion) based on a sample statistic. The level of confidence is usually set at 95%, meaning that the interval will contain the true population value 95% of the time if the sampling and estimation procedures are repeated many times.
