Applied Statistics (Entire Course) - Statistics - 8.2 Student's t-Distribution

In this video, we explore a probability distribution model closely related to the normal model. It is called the student's t-distribution. We will use this in scenarios where we are trying to estimate a population mean but do not know the population standard deviation (sigma). 0:00 Intro 0:04 Where did the t-distribution come from? 1:49 Student's t vs. Normal 3:08 Find Critical t-Value with Given Area to Left or Right 6:17 Find Critical t-Value with Area in Tails or Between 8:48 Practice Using Excel 13:06 Up Next Power Point: https://bellevueuniversity-my.sharepoint.com/:p:/g/personal/kbrehm_bellevue_edu/EWCEmRq-whxGgrBP9-HL3jwBgkWs-i074OSTs0cTh2Acdg?e=kQpcSI Confidence Interval Decision Tree: https://bellevueuniversity-my.sharepoint.com/:b:/g/personal/kbrehm_bellevue_edu/EbcsvXnQcsxAjGEmqReLNS4B-bxNVp6EzXRPrsFLxbaUSQ?e=ehmDq1 This playlist follows the text, Beginning Statistics, 3rd ed, Warren, Denley, Atchley Playlist: https://www.youtube.com/playlist?list=PLl-gb0E4MII1dkfGxmdt8YA0Dgabdvdmq
