This document discusses hypothesis testing for a single mean. It explains the steps for conducting a hypothesis test on a single mean: 1) State the null and alternative hypotheses, 2) Choose a significance level, 3) Select the appropriate test statistic (z-test or t-test), 4) Identify the critical region, 5) Calculate the test statistic, and 6) Make a conclusion about whether to reject or fail to reject the null hypothesis based on where the test statistic falls relative to the critical region. It then provides examples demonstrating how to conduct hypothesis tests for single means.
