The Sample Size Determination Statlet in Version 17 calculates the required sample size for estimating and testing various population parameters. These include normal means and standard deviations, binomial proportions, Poisson rates, correlation coefficients, and the capability indices Cp, Cpk and Cpm. The sample size may be based on the desired precision of an estimate or the desired power of a test. Both two-sided and one-sided requirements can be handled.
