μ1 μ2 the two population means are not equal. Power is calculated as the power achieved with the given sample size and variance for detecting the observed mean difference with a two sided type i error probability of 100 ci dupont 1990. Effect size interpretation describing the critical value corresponding to small medium and large effect sizes. μ1 μ2 the two population means are not equal.
