My teacher who was trying to teach us this content had over an hours' worth of content that still failed to accurately explain how to do this, your video was so much more helpful, thank you!

6:25 all of this is a great walk thru but the interpretation is incorrect. The correct interpretation is that for 95% of all random samples, the confidence interval will contain the population mean.
