What's the point of finding the z score exactly?
@dmcguckian 3 күн бұрын
The z score enables us to look up the probability using a z table (or Calculus or an app that calculates the area under the normal curve). Without the z value, we would have to use the binomial distribution which is computationally difficult even for powerful computers. It’s less of an issue with today’s computers but it used to be near impossible to do the calculations by hand for problems with large n values. Even fairly powerful computers struggle to do the work quickly, so programmers might still opt to use approximations like this in their code when speed is more important than precision.

Easiest way to explain it in my opinion is the contestant should NOT want to guess correctly at the start and because 2 of the 3 doors are empty that means the contestant has a 67% chance of ending up with an empty door which is good. If you guessed an empty door correctly, the only door left after the next step is the door with the prize.

The equation changes as soon as you offer the option of switching, the option is either blue box or yellow box in reality, which is a 50/50 chance of being both right and wrong. very simple.

I’d like to just say you have given me hope that I can keep my 4.0. I’m studying for my statistics cumulative final and could not for the life of me remember CLT. I was getting so frustrated trying to work it out on my own and here this video popped up and by the end of the video I can confidently say I remember the application! Thank you so much for making videos like this and explaining so clearly without being condescending 🤍 p.s the way you write your fives had me entranced 😂
