This document provides an overview of one-sample hypothesis tests. It defines key terms related to hypothesis testing such as the null and alternative hypotheses, test statistic, critical value, Type I and Type II errors, and p-value. It explains the five-step hypothesis testing procedure and how to set up hypotheses for tests involving a population mean or proportion. Examples are provided to demonstrate how to conduct hypothesis tests about a population mean when the population standard deviation is known or unknown, and how to conduct a test about a population proportion. The document also discusses how to interpret p-values and the concept of Type II errors.
