Howdy!
I've been creating free Mathematics videos since 2007 and continue to do so.
Teachers please feel free to reach out if I can help you although I do get a lot of emails! You can find my email below next to the 'For Business Inquiries' box!
If you are a business or organization who needs consulting help or video creation just let me know as I'm happy to discuss.
Thanks to everyone who provides constant love and support. I truly appreciate it and it is why I keeping doing what I do.
Cheers my friends and happy studies!

Hypothesis Test : 'Performing a Full Hypothesis Test, Ex 1'
In this video, I show how to perform a one-tailed hypothesis test. In this video we discuss: formulating the null hypothesis and the alternative hypothesis, test statistic, one-tailed and two-tailed hypothesis testing, the central limit theorem, the decision rule, type 1 error, level of significance and more.
This video would be suitable as a nearly full lecture in a statistics class with a few extra supplemental examples.

but why?
hello, does anyone know what kind of note taking website/app he is using?
And with a sharpie?
U aploaded in 2010...and it is useful for me in 2024..... Take love broo❤
fucking genius
The answer about your solution isn't that bro, it's 12.2234
how is he so damn good!
x²+2x-8≥0 (x+4)(x-2)≥0 x+4=0 x=-4 x-2=0 x=2 Test x=-5 (-5+4)(-5-2)≥0 (-1)(-7)≥0 7≥0 true Test x=0 4•-2≥0 -8≥0 false Test x=3 (3+4)(3-2)≥0 7•1≥0 7≥0 true x≤-4 or x≥2 ❤
Are you teaching or rapping? 😒 How do u convince someone to learn it this way.
Poor souls 😂😂😂😂😂😂😂😂😂😂
I’m still confused, how do I know if the phase shift is going left or right depending on the problem?
I'm tired of being dumb.
Simple and. Precise
My life has been saved
hell yes. We're getting out of calc 3
6:28 Why does 84-84 = 0! (?) 0! = 1 Is ! an exclamation mark or math symbol
6:35 g(x) -> g(5) also works. Not just g(-2). Do I write x = -2, x = 5?? Nevermind, the equation gives you the rest anyway, so I don’t need to find two function values of zeros, just one, fortunately 😊 Then keep doing synthetic division
2024 comment :D ty for ur vids
Just to confirm, can anyone tell me if the answer to this was 7pi/30?
why does f prime of x doesn't include dx any more? Does anybody know? Same question for g prime of x. Why doesn't it multiply with dx anymore?
This is gold
I like it!! It is very useful.
Thanks sir. So good
Okay-first off. Your videos are amazing. Learned so much math from you over the past decade or so. One question-what prompted you to switch from white paper and marker to digital with a black backdrop? Also, your voice sounds different-is this still “you”? Anyways, thanks for the past decade of help 😊
He literally explained in 6 minutes what my teacher couldn't in 3 hours
Thank you for the video!
So this is an alternative to the method where we need to find two numbers that add to make (in this case) 6 and multiply to make 8?
same way people believing in god
i love you so incredibly much
Pardon me if I am slow, but why do we isolate the second integral and not the first one?
Bro its wrong it is in dependent k3=0 in this case
Isn't a = 0 for maclaurin series not taylor
You can multiply all the denominators to make it easier :)
And yes..... This video was recommended to me for no reason. 👍
ChatGPT told me about you!
this guy is good he should invest in a wiper
literally the best use of my time and fantastic explaining, really loved this tutorial 15 years later thanks a ton man
What if we have A(123456),B(345710),C(4568910) Element (AnB)NC but it has a subscript
a little too fast...
respect my guy! saved my ass fr
Thanks 🙏🏻🙏🏻
hey, am i just really dumb or why does he replace dx with just straight um du and not dx = du/2x?? he didn‘t consider the 2x did he?
Absolutely
Sin x + cos x = 1 For 14
Excuse me here!!! How do i derive the R1 thingy formula Is it a general formula or A formula I'll have to derive myself
I have been looking for help on YT for a week now!!!! thank you!!! that looks so simple when you do it. you saved me!! :)
thank you so much , it was special way to introduce , I like light on the papers, It makes their color beauty, and the most important i have understanding this lesson last , thanks a lot ❤🌷
sorry Patrick, I just wanted to let you know that at 0:59, that 4 is not negative but it is positive
Btw 👍
