CONFIDENCE INTERVAL Calculator WITH STATISTICS

Fill in the sample size (n), the sample mean (\(\bar{x}\)), the sample standard deviation (s), and the confidence level (CL). Write the confidence level as a decimal. For example, for a 95% confidence level, enter 0.95 for CL. Then hit Calculate and assuming the population is normally distributed, the confidence interval will be calculated for you.
