Applied Statistics (Entire Course) - Statistics - 11.1.1 Hypothesis Testing for 2 Sample Means (σ known) - 1-Tailed

Often the hypothesized difference will be zero, as we will be interested in determining if there is a significant difference in the two samples. 0:00 Intro 0:21 Reference Sheet 2:32 Example 1 - Problem Statement 6:42 Example 1 - Check Conditions and State Hypotheses 8:03 Example 1 - Calculate Statistics 10:15 Example 1 - Draw Conclusion and Interpret Decision 10:50 Example 1 - Support with Confidence Interval 12:29 Setting up Excel 15:27 Example 2 21:52 Example 2 in Excel 22:25 Up Next Power Point: https://bellevueuniversity-my.sharepoint.com/:p:/g/personal/kbrehm_bellevue_edu/EZ08Jz8qUdBJv8P4rKTS0KMBknYUhlIBaThGzHQqun4apQ?e=dJQR4H Confidence Interval Decision Tree: https://bellevueuniversity-my.sharepoint.com/:b:/g/personal/kbrehm_bellevue_edu/EbcsvXnQcsxAjGEmqReLNS4B-bxNVp6EzXRPrsFLxbaUSQ?e=ehmDq1 Hypothesis Testing Decision Tree: https://bellevueuniversity-my.sharepoint.com/:b:/g/personal/kbrehm_bellevue_edu/Ea6wo_3qR69HqiKzJBvsCY8Bn1HBDw8thED70zuAhU81CQ?e=IgbeO4 This playlist follows the text, Beginning Statistics, 3rd ed, Warren, Denley, Atchley Playlist: https://www.youtube.com/playlist?list=PLl-gb0E4MII1dkfGxmdt8YA0Dgabdvdmq
