    Confidence Interval for a Population Mean Given Statistics

    This calculator creates a confidence interval for a population mean given statistics. Please report the error to Dr. Jessica Kuang at jkuangATvcccd.edu.

    To learn how to use this calculator, please watch a short video here.

     

    Input

    Fill in the sample size (\(n\)), the sample mean (\(\bar{x}\)), the sample standard deviation (\(s\)), and the confidence level (CL), then click Calculate.  Write the confidence level as a decimal.  For example, for a 95% confidence level, enter 0.95.
