In this first video where we perform hypothesis testing, we will TAKE OUR TIME and talk through each aspect of how to perform a hypothesis test for population means where sigma is known. There is a difference between a one-tailed test (either right or left) and a two-tailed test. I talk through the process and differences in much more detail for this section than I do in subsequent sections, so don't be afraid to re-watch any of these videos to make sure you have the concept down. 0:00 Intro 0:07 Overview of Hypothesis Testing Steps 0:15 Reference Page 3:05 Example 1 - Problem Statement 5:06 Example 1 - Check Conditions and State Hypotheses 6:18 Example 1 - Gather Data/Calculate Statistics 10:26 Example 1 - Draw Conclusions and Interpret the Decision 11:36 Example 1 - Support with Corresponding Confidence Interval 14:41 Setting up Excel for One-Tailed Tests 19:53 Up Next Power Point: https://bellevueuniversity-my.sharepo...
