Sample Size Calculation Premier from premier-qms.org

For a test with \alpha = 0.05 and \beta = 0.10, the minimum sample size required for the test is n = (1.645 + 1.282)^2 = 8.567 \approx 9 \,. Choose which calculation you desire, enter the relevant population values for mu1 (mean of population 1), mu2 (mean of population 2), and sigma (common standard . For the power analyses below, we are going to focus on example 1, calculating the sample size for a given statistical power of testing the difference in the .
