This document discusses significance testing and hypothesis testing procedures, including: 1) The objectives of hypothesis testing are to test claims about population parameters by stating hypotheses (H0 and Ha), calculating test statistics, determining p-values, and considering significance levels. 2) Examples of one-sample and two-sample hypothesis tests are provided, including a test of whether a population gained weight on average and a test comparing the means of two samples. 3) Statistical tests discussed include the t-test (for comparing two means), z-test (when population standard deviation is unknown), and chi-square test (for testing goodness of fit to an expected distribution). Formulas and procedures for conducting these tests are outlined.
