can you include ANOVA TEST?

[@chitandaeru2948]

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.

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

My *favourite online teacher* 💓💓💓

[@chelecovers6893]

You. Have. Saved. My. Whole. Life. I can never thank you enough. wow.

[@TimeQuxxn]

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

[@abby454]

Happy teacher's day, The Organic Chemistry Tutor!!! :)))

[@gracesmyth6040]

You just saved me from failing my stats test. Thank you!!

[@llaaaza1911]

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.

[@codeguy21]

Sir plz tell how to watch your organic chemistry lectures in order. In playlist also there are many organic chemistry which to watch

[@shangbiedu6408]

Thanks Mr organic chemistry tutor!!!!

[@BeyondNoise9]

Amazing !! What a teacher !

[@牛奶鳳梨]

how is this dude teaching literally every subject😶

[@st4pps]

im trying to get 1.96 on the Z table but it doesnt match up?

[@mangeshjadhav3731]

Big thanks. This helped a lot :)

[@aeriiful]

i hate school

[@isabelfeng6707]

can never thank you enough

[@carolinacastano7210]

Where did you get the 1.96 from

[@shreyamrohix4420]

Area to the Left = 1 + CL / 2. I believe look for 0.975 in the Z Table.

[@ameniasinavodre8619]

yes brother you are right..God Bless From Fiji ​@@shreyamrohix4420

[@TawhidShahrior]

life savior dude!

[@Lakostus31]

I love you so much ❤️❤️❤️ thaaaank youuu

[@dimitriysevryukov1629]

Thank you very much !

[@weljohnplayz]

Is it true that if n>30 and the Population standard deviation is UNKOWN, in this case use the T-Distribution?

[@_._kroks_._]

I was thinking if this was a mistake? It is right?

[@weljohnplayz]

​@@_._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

[@_._kroks_._]

@@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

[@weljohnplayz]

​@@_._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.

[@_._kroks_._]

@@weljohnplayz yeah this man saved me too. Still waiting on my grades tho but I'm hopeful

[@RaulSouza12w]

I love this channel, help me a lot, thanks a lot !!!!

[@СанжарАлманов-т3с]

Thank you bro!

[@OPANYIAUGUSTINEOBALA]

It really helped

[@alexiscrause5228]

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

[@54.5mviews3]

use Z calculated instead

[@amarmata1]

How are you typing in the number on calculator, I'm getting a bunch of zrtos

[@moodyabushaqra1115]

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!!

[@Jupiter1423]

The normal distribution curve is one of the most important things to know.

[@LabibHasanBayzid]

P - cap = sample proportion P = population proportion

[@rayraygonecrazy1571]

Thanks this helped me

[@atod2572]

But what does q stand for? And is it capital P or small p ?

[@alexiscrause5228]

q = 1-p small p is the proportion Capital P is the probability

[@DanielDuhon]

So what the heck is p^ and how is it different than p?

[@jessiemayfield6749]

Ok but my questions don’t have the confidence level, they’re like = ot= at a=#

[@miguelwsth]

😊

[@XAUGEEK]

So 50 is the statistic?

[@g12-sharamayjeano.joaquico87]

can someone can help me to solve this problem i really need this later morning

[@jakeaustria5445]

Give me a problem and I will solve it for free. I need practice for my Stat Course, so it's a mutual benefit.

[@dinmadaniel9830]

what if s was not given

[@michellevenegas4031]

i love u

[@pinkcactus669]

How do we determine which tailed test to use?

[@ngoducloinguyen3745]

you can check the previous video in the playlist

[@Xighthought]

Nah im cooked😮 the quiz will be held later and still i don't get it

[@bossxx2123]

I still don’t get it🧍

[@RafiaKhan-ti2pm]

Just like me😢😢

[@sutheen]

Mmm have Tim.

[@aeeeshatuh]

[@miltonfriedman1912]

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.

[@llaaaza1911]

Maybe ask nicely.

[@CG-uh9zc]

Nice accent. I can barely focus on the lesson
