can you include ANOVA TEST?
Whoever is making these videos, God bless them. What I couldn't learn in a classroom, I could learn from a stranger on the internet. Blessed.
Literally learned this in my 8 am today and I was so confused. A literal blessing that you posted this a few hours later!!! You should do the next section too
Happy teacher's day, The Organic Chemistry Tutor!!! :)))
My *favourite online teacher* 💓💓💓
You. Have. Saved. My. Whole. Life.
I can never thank you enough. wow.
1:17 let's say we're dealing with a 95% confidence level, you can use the standard z table to get the critical value
to decide whether you would accept or reject the null hypothesis you need to get another z value, a calculated z value, and compare it to critical value
1:58 if Zc is to the right of z, then that means you should reject the null hypothesis
You just saved me from failing my stats test. Thank you!!
Guys, the values he is using are just arbitrary numbers to explain the work. Don’t get stuck on where it came from. It’s just an example.
Sir plz tell how to watch your organic chemistry lectures in order. In playlist also there are many organic chemistry which to watch
Thanks Mr organic chemistry tutor!!!!
Big thanks. This helped a lot :)
Amazing !! What a teacher !

im trying to get 1.96 on the Z table but it doesnt match up?
I love you so much ❤️❤️❤️ thaaaank youuu
Thank you very much !
can never thank you enough
i hate school
I still don’t get it🧍
Just like me😢😢
Mmm have Tim.
I also didn't get it but now I get it that I have exams next week 😅
@@aeeeshatuh explain it to me brudda 🙏 I've been watching vids for days and I'm not getting it. Makes me feel dumb af😭
Wow! This is so easy, thanks for the explanation. In 2 days I watched almost all the videos of this list. It's so easy to understand, even for me that I am 13.
life savior dude!
Thank you bro!
It really helped
Where did you get the 1.96 from
Area to the Left = 1 + CL / 2. I believe look for 0.975 in the Z Table.
yes brother you are right..God Bless From Fiji @@shreyamrohix4420
I love this channel, help me a lot, thanks a lot !!!!
Hi Sir, your videos are an absolute saving grace! Thank you. I wanted to ask if there will ever be an instance whereby we are dealing with proportions and n
use Z calculated instead
Hello sir I love your videos thank you so much, can you please do Quantum mechanics I need it, I love the way you explain the material thank you!!
How are you typing in the number on calculator, I'm getting a bunch of zrtos
The normal distribution curve is one of the most important things to know.
Thanks this helped me
Is it true that if n>30 and the Population standard deviation is UNKOWN, in this case use the T-Distribution?
I was thinking if this was a mistake? It is right?
@@_._kroks_._ at this time I was confused 'cus my teacher use the same problem n>30 sd is unknown and she use the T-test/distribution and I was like "wait what?!" sometimes the teacher made a mistake or maybe I am, and yeah at that situation I follow my teacher, but in final exam I use the Z-test/distribution 'cus I trust this man who helped me a lot of my school days
@@weljohnplayz my topper friend cleared it later saying if n>30 and we use the sample SD the z and t test gives almost identical answers
@@_._kroks_._ True, it's almost identical answer and they have different formula. Thanks to this man becuase of him my grade in math got higher than my expected.
@@weljohnplayz yeah this man saved me too. Still waiting on my grades tho but I'm hopeful
Ok but my questions don’t have the confidence level, they’re like =
ot= at a=#
So what the heck is p^ and how is it different than p?
But what does q stand for? And is it capital P or small p ?
q = 1-p
small p is the proportion
Capital P is the probability
what if s was not given
So 50 is the statistic?
😊
can someone can help me to solve this problem i really need this later morning
Give me a problem and I will solve it for free. I need practice for my Stat Course, so it's a mutual benefit.
Nah im cooked😮 the quiz will be held later and still i don't get it
How do we determine which tailed test to use?
you can check the previous video in the playlist
i love u

Where are you from? I hear a slight accent.

I don't get anything. You don't explain where these numbers come from, nothing about the formulas. I could have read this stuff on any website. Can you please explain more of what you're doing? I find this video quite useless otherwise.
Maybe ask nicely.
Nice accent. I can barely focus on the lesson
