Inferences About Two Population Means, Sigma Known Part 1

This tutorial covers inferences about two population means when sigma, the population standard deviation, is known.  The tutorial covers confidence interval estimation for sigma known, and hypothesis testing for sigma known.  Both the critical value approach and the p value approach are demonstrated.
