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)

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

Very good video, clear explanation. Thank you.

Thank you so much.

thank you very much .....

Thank you!!!!

THANK YOU

excellnt

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

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.

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

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

under which conditions does one resort to t-dist?

Big mistake to politicise maths. Keep it neutral 🤦🏻

@@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 🤷🏻

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.

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.
