This is the most incredible UA-cam instructing channels to ever exist. I have been on the brink of so many mental breakdowns, and every time I turn to the Organic Chemistry tutor. This channel has saved my sanity, my grades, and my future too many times to count. Thank you so much for everything you do. You are doing a great service to the world by making these silly little videos. Thank you.
I just completed my degree and have to say 'The Organic Chemistry Tutor' is a OG. He's been a great help in all topics whether its maths, physics, chemistry throughout the 4 years at uni.
Thank you so much ive been going to engineering schooling for 7 years and have watched you from multiple topics in science chemistry and engineering courses. You are a very good teacher and have helped me through many tough times in college thank you very much!
I just want to say thank u for your lessons, you've helped me out a lot in school. I just want to tell u that your doing a great job, please keep the lessons coming your fantastic. Thanks to u I was able to pass my exams ❤😊👍👍👍👌
Wow! Just wow! You explained this very well. You broke it down and explained the fundamentals, which increased my understanding of this subject so much. You did this all in 17 minutes while my professor just talks too much about theorems in an hour and 15 minutes and doesn't go over example problems too often. You are the best.
you are a gifted teacher sir. God has given you this gift. you are so generous that you are offering us these pearls without hoping for anything back. Honestly grateful for you!
I salute to you buddy. The way you linked the concepts was literally amazing. Eg: You stated in your previous video that according to CLT if normal distribution, and iff n>=30, there will be a good approximation of the sampling distribution to the normal distribution. And now how you stated then if the n
thank you thank you thank you . i have been failing my stats class and i felt like i have been falling way behind to ever catch up and watching your videos have helped me catch up in a couple days.
Wow thank you. The standard deviation formula part is what helped me the most which I couldn't search on my textbook or anywhere else lol. Thank you very much!
I don't know why teachers are paid those salaries to make things more horrible which otherwise can be explained this simpler way. Thanks God for saving me 🙏
I know you have passed your degree, but replying for those who will have the same question, when we are dealing with sample, we take 'n', and when dealing with population, we take (n-1), here the whole class is of 10 students, and we are dealing them, so this is population, if we take a sample of 4 students from whole class of 10, it'll be sample.
Pls solve this for me In a random sampling of 600 students selected in a school, It was observed that 420 have a fan in their hostels. Construct a confidence interval at 95% for the entire students that does not own a fan
thank u for ur videos, 1 quick question, if u r using alpha/2 for significance level, shouldn't u be using two tailed significance level (error) at t-distribution table, but u r using one tailed, why? for example on ur last example a/2=0.05 and t-value should have been 2.262 but u used 1.833, please explain asap because we have exam, and also a/2 is for two tailed distribution why r u using a/2 for one tailed distro. thank u, much appreciate ur dedication and word, GOD bless u
Is it correct to say that regardless if the test to be employed is a 1-or 2-tailed test, the EBM will always employ alpha/2 in determining the value to be located on the t-table?
@8:00 you making confidence interval with 97.5% of confidence and not at 95%. if you are taking 1 one tail alpha, then confidence level is also 1 tail. And 1 tail alpha 0.025 correspond to 97.5% one tail confidence. Please correct me if i am wrong.

you are a freaking genius !!! you explained in 17 minutes the topic that my professor can not explain in 2 hours. Thanks a lot !!
my professor just said (used mini tab)
You're right
Maybe you should pay attention in class then

This man deserves a Nobel teaching prize!!!
True that!
Man you have opened my eyes now my confidence level for statistics is 97% from understanding symbols to use, conditions, nuances etc. 😭🙏🙇♀️🙇♀️🙇♀️

Who else is watching this at 2:00 am night before the exam?
11am 1hr before the exam
01h17.
Naneun
watching this 20 mins before the test
Watching this during the exam
You’re the best man, thank you for all your chemistry and math lessons
Thank you so much> >>> i was literally crying cos I didn't understand T-distribution. Thank you so much for doing such a great job
Wow thank you. The standard deviation formula part is what helped me the most which I couldn't search on my textbook or anywhere else lol. Thank you very much!
You’re an Angel sent from heaven, thank you !
even after years, TheOrganicChemistryTutor video is like gold mine
My guy is the best🎉🎉🎉🎉🎉🎉🎉🎉🎉such a sweet explanation, u deserve a gift on my graduation day

Just know doreen nabuuso is proud of u,im from uganda at kyambogo university
This was really helpful! Thank you!
thank you very much for this wonderful video :)
Thanks a lot You are AWESOMES
Great explanation. How would I find the p-value?
thank you teacher.
Very interesting . Thanks.
Hie. May you please explain further on how you Decide which one to use normal distribution or student t distribution .
You are Amazing!!!!!
Thanks a lot!!
Thank you
Thank you. This helped my on in stats a lot!
Thank you so so much.
Am greatful for the lesson
Why do we use n-1 while finding the standard deviation???
I know you have passed your degree, but replying for those who will have the same question, when we are dealing with sample, we take 'n', and when dealing with population, we take (n-1), here the whole class is of 10 students, and we are dealing them, so this is population, if we take a sample of 4 students from whole class of 10, it'll be sample.
Pls solve this for me
In a random sampling of 600 students selected in a school, It was observed that 420 have a fan in their hostels. Construct a confidence interval at 95% for the entire students that does not own a fan
Thank you very very much thanks
I calc numerous times. How did you get s=11.709?? I used your method and my number everytime was much larger than that
When you divide alpha in 2, isn't that a two tailed test? Why do you say that this is a one tailed test?
You're right, if you overlook that error it works out
yes exactly
No man, two tail test is basically for hypothesis testing when we assume that the man is not equal to any value i.e., it can be less, or more
thank u for ur videos, 1 quick question, if u r using alpha/2 for significance level, shouldn't u be using two tailed significance level (error) at t-distribution table, but u r using one tailed, why? for example on ur last example a/2=0.05 and t-value should have been 2.262 but u used 1.833, please explain asap because we have exam, and also a/2 is for two tailed distribution why r u using a/2 for one tailed distro. thank u, much appreciate ur dedication and word, GOD bless u

Is it correct to say that regardless if the test to be employed is a 1-or 2-tailed test, the EBM will always employ alpha/2 in determining the value to be located on the t-table?
Masterfully explained! Thank you.
I have a question at 05:47. Is it alpha / 2? Or just alpha?
If I'm not mistaken, it's alpha. Am I wrong?
Excellent!
can you keep the t distribution table and by the way nice explaination
@8:00 you making confidence interval with 97.5% of confidence and not at 95%.
if you are taking 1 one tail alpha, then confidence level is also 1 tail. And 1 tail alpha 0.025 correspond to 97.5% one tail confidence.
Please correct me if i am wrong.
Do you know if he was correct about this?
I love you. Thank you
thanks for this!
How can we decide to use whether alpha or alpha/2 ?
Thank you so much.
What if your degree of freedom is a decimal? What do you do by then?
thanks
Thank you so much
error bound mean (EBM).
