do you have any videos focusing on the linear regression topic, also a video how to interpret everything? Im just worried im not gonna get full credit since the answers to questions are always so specific. Thanks !
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😭😭🙏
Thanks for the explanation boss. Taking this exam tomorrow and this might’ve been the dagger.
I have mine in 2 hours😭
@@SchonEgamiLet us know how it goes!

good luck, you got this, report back to us too!
@@SchonEgamiYou got this dude!
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.
Thanks and dang I said 4 and showed work for 4, but had 3 written down!!! My mistake, thanks for pointing out!!!
Exactly what I needed thank you!
This is crazy helpful, thank you so much!
You're so welcome!
THANK YOU SO MUCH! i might not fail this exam... 🤭
You got this!
Hey Mr. Porinchak for 19:30 why do we use x=4 and not x=3?
It was a typo. Sorry!!!
tysm for this video! can you make a video about all calculator functions (ti84) for stats please?
Working on a playlist of that right now, here is what I go so far

@@mporinchak thank you!!
this is so helpful!! thank you so much!!
could you make the same video for casino cg50? please it will be really helpful
I wish I could but I unfortunately am not proficient on using that calculator! Sorry!!!

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?

do you have any tips for interpretation question? for example, how do you interpret s or r^2
here is a video that explains it
