im taking the test on tuesday and understand if you dont get back to me by then. but my question is: what is the point of using z score (example the question 13 minutes in) instead of just plugging in the numbers (Lower: 35 upper:10000 Mean: 30 SD: 5) ? My understanding is that you can do either way. Nonetheless, ive been watching all of these review videos and just want to say thank you very much man this is so helpful
You are right. I teach my students to show the work for the z score and then use it. Especially for students who have to use a z table to find probabilities
I’m watching this 30 min before the exam and you are my savior
Finished the AP STATS today!
