Class notes MATH 3450 Principles of Biostatistics Chapter 6

Document preview thumbnail
Preview 3 out of 29 pages

This educational guide details the practical application of hypothesis testing using a graphing calculator, specifically focusing on how to navigate the STAT TESTS menu to perform T-tests and Z-tests. The material visually demonstrates the distinction between the critical region, where one would reject the null hypothesis, and the non-critical region, where one would fail to do so based on the test statistic and alpha level. By providing step-by-step screenshots of a TI-84 Plus CE, the source illustrates how to input raw data or summary statistics to calculate essential values like the p-value and t-score. Ultimately, the text serves as a technical bridge between theoretical biostatistics concepts and the computational tools used to determine the statistical significance of experimental results.
