Great question! The answer is kind of! :) When calculating a confidence interval, you'll need to use either z* or t* to do the calculations. Larger values of z* or t* make the interval wider (more confident) and smaller values make it narrower (less confident). Knowing what a z-score is makes z* a little easier to understand. I can link a few videos below where I explain z* in depth!
Here's the intro to confidence intervals (I don't quite get into z* here, I just use a nice whole number for z* so you can focus on what a confidence interval actually is. Definitely make sure you understand what a confidence interval is first.) ... ruclips.net/video/Dn7br_62GNk/видео.html
Simplicity is the real winner here. Lights and animation, don't count. It would be nice, if you would make another video that contains more samples. One where noobs can decipher from the language, what needs to be done.
Thanks for the comment! When you say more samples, do you mean more examples of AP problems? Maybe with a focus on determining what the questions are asking you to do?

Insightful video presented nicely ❤
There are also z-scores involved when calculating confidence intervals. Are they the same thing?

And then here's where I explain what z* is (starting at 6:13) ... ruclips.net/video/Yd32IpeNPJM/видео.html
