Thank you for these review videos for the exam. ⭐ Very minor mistake, but for the binomial distribution portion you put 4 successes instead of 3.

[@mporinchak]

Thanks and dang I said 4 and showed work for 4, but had 3 written down!!! My mistake, thanks for pointing out!!!

@@mporinchak Thanks!

[@zanp2272]

26:09 Im curious why use t test instead of z bc sample size size is larger than 30. Cant we assume to use z test accordingly?

[@mporinchak]

Greater than 30 sample size isn’t the reason why we use a z test versus t test. If you don’t know the standard deviation of the population only the standard deviation of your sample you must use a t test.

@@mporinchak wow! I think i am confused with the condition for normal distribution for sample. Thanks for the new knowledge at the last night. I never know that thanks a lot😭😭🙏
