22.8: Sample Size for a Mean Calculator
Sample size Calculator
Fill in the population standard deviation (\(\sigma\)), the error bound (E), 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 necessary sample size will be shown.
