Introduction to Hypothesis testing for Normal distribution | ExamSolutions

[@chersymale]

Spent an hour reading the notes and trying to figure this out, then I searched for it on UA-cam, found this awesome video and understood it in less than 15 minutes. Thanks for the great video!

I think so.

[@SimersTO]

I have an exam in a few hours and this happens to be one of the topics covered, thanks for clarity!

[@hannahclarke9902]

I have an A level in two days and needed a quick recap :') ur a legend dude thank u

[@flo6865]

Thanks for the straightforward explanation and including the calculator!

[@geraldidzakwan8666]

I just understand what p-value is about from this video, thanks a ton!

[@c.1304]

Thank you for making this! I finally get when to reject/accept the null hypothesis

[@eri4232]

thank you so much!! your explanation was amazing compared to the other videos I watched, you saved me here

[@kiwihour333]

If it is a 2 tailed test then use the P(xbar > or < value) based on whether or not xbar is less than or greater than u. (less than u, means P(xbar < value) and opposite for greater than u)

[@austinchan4575]

Thank you so much, you teach better than my teacher does!

[@tomcowen376]

been trying to understand this for hours, finally clicked because of this

[@Nicolettethegreat]

I was so stuck. This helped me a lot

[@rahatkhan919]

Very good video, clear explanation. Thank you.

[@samad5125]

Great video man I was waiting for this topic for soo long

[@davescruby30]

really useful video, thanks

[@jasminedaniels9503]

Great video and revision-thank you tons :)

[@MrLProductionsOfficial]

Stats final in 3 days for A-Level Math course in one year. Really need to pass this to get an A*. I think this has helped, thank you.

[@jaigoyal2794]

Thanks a lot - really helpful!

[@IDGOCH]

Thank you so much.

[@Louise-vk6gl]

Very useful, thank you!

[@freddierobinson9587]

is it written X bar N(mean, (standard deviation)squared, divide by n) or is the squared squaring both the standard deviation and the n ? so (standard deviation/ n ) squared. Thank you in advance

[@freddierobinson9587]

I get it now , dont worry :)

[@tiegan7158]

It's hard to tell if the xbar ~ N(mu, 6²/n) or if the 6 is sigma

[@ExamSolutions_Maths]

It's a sigma not 6

thank you very much .....

Thank you!!!!

What happened to Stuart sidders

[@thesuitedsaltshaker8388]

thank you sm

[@benstokes3760]

Nice vid. This is a different person speaking tho right compared to the OG exam solutions?

[@ExamSolutions_Maths]

Thanks Ben. Yep different guy. I'm Michael. The OG has now retired.

[@jasonnwokeji4107]

@@ExamSolutions_Maths i want to personally thank him for his service!!

[@jacobsuresh3743]

nice one bro btw u added a david moyes interview to the normal distribution playlist

[@ExamSolutions_Maths]

Thanks for the heads up bud.

[@fahrenheit2101]

Why is the sample mean distribution's variance divided by the number of samples?

[@ExamSolutions_Maths]

YOu can see the proof in this video ua-cam.com/video/LcEazP4926U/v-deo.html

[@rajakumaran9933]

excellnt

[@omarkhan1970]

Is this suitable for the CIE exam board for A level

[@ExamSolutions_Maths]

For the CIE exam board, you'll need to know how to conduct hypothesis testing for Binomial and Poisson Distributions.

[@brettncube4564]

under which conditions does one resort to t-dist?

[@Hello_there_obi]

Big mistake to politicise maths. Keep it neutral 🤦🏻

[@ExamSolutions_Maths]

Oh dear

[@Hello_there_obi]

@@ExamSolutions_Maths just saying. Politics don’t belong in the classroom. Unless it’s a politics class lol. But even then you can’t show overt bias 🤷🏻

[@offixial_jj3573]

I think it is fair to politicise maths especially for normal distribution as it makes it easier to understand. Analogies are useful and maths is used everywhere.

[@offixial_jj3573]

Though , it would've been better to use another analogy (not coronavirus) as this topic can be sensitive to some people... just saying, but you did use other examples too anyway. Thanks examsolutions for your content, I have been making use of your channel as my exams are coming up, it has been helpful.
