Thank you so much, I was having trouble understanding what really P-value mean and you made it very clear with going back to it again and again. You also cleared my concept about z-test, our teacher just tells us about the formula and what to do but never tells us why we are doing the tests and what they really mean which bothers me so much. Great teacher, great explanation.

At about 6:20 I was checking my headphones and volume, but oh do these videos help, thank you these ease my frustration

thank for your video. What about the condition n>= 30 ?

I don't understand how to find a p value! could you explain it in a simple way! thanks

We use 99 as upper bounds bc sam thinks its higher??

This is helpful, but it would be nice to have the equations to be seen and not you just writing in the numbers that are no longer on the screen. By the time you get to the next screen, I've forgotten the previous numbers. Maybe I'm getting old. LOL

Your vocab at the end, it says, "Statistically SIGNIVGICANT"
Fix that?
Also these videos are excellent at grasping concepts. A lot of this is much easier using calculator functions, e.g. 1-prop-Z-int, but this makes it so much easier to understand the big picture, and the WHY.
