Hypothesis Testing for Mean with Known Standard Deviation (Example 2)

This statistics video explains an example of hypothesis testing for means with known standard deviation. We work through an example of a hypothesis test where the population standard deviation is known. Our example involves testing a claim that a system lasts less than a particular amount of time before needing replacement. 0:00 Introduction 0:59 Hypothesis statements 1:31 Finding Z-critical 2:45 Calculating test statistic 3:41 Comparing statistic to rejection region 3:55 Writing the conclusion statement Example #1 Video: https://youtu.be/kzT1NAgV6-M Houston Math Prep Statistics Playlist: https://www.youtube.com/playlist?list=PLbYOkEbzW903okrN7cDLhmjOoiiTAw6gz Houston Math Prep YouTube: https://www.youtube.com/user/HoustonMathPrep
