From Freesciencelessons dude, to Mr Bruff and now Jack Brown. Legend to all high school kids💯💯💯

[mattdriver]

No one explains this better on YouTube, thank you!

I didn’t have much hope at the start of the video but you’ve raised my confidence in 11 minutes more than my teacher has for a month!

I am a first year Finance student, Hypothesis testing had baffled me until now so thnkyou for explaining it so well.

[parsa]

youre a geezah, thanks for the help my dude

[nina_o]

This was extremely helpful! I finally understand how to answer these questions. Thank you!

[raahimomer]

3 hours before exam and this guy never fails to come in clutch. ♥♥

[franklinhole]

Thank you so much for this. Very clear and easy to understand :)

[ajpsaint]

What a Legend! Such a clear explanation

[KazACWizard]

thank you so much, im doing a levels and my f maths teacher cant really explain this well, and you just saved my grade bc i suck at stats.

Hello sir
I have one question. In which case do i need the bpd and when the bcd button?
Thank you

[Daniel-momm]

Hi sir, are you able to use Critical Reigons instead of finding the probability, if not can you explain why and how to differentiate when the question is asking to test against the critical reigon and when it wants the test to be tailored to the Significance level.

Thank you so much for this video. You helped me to solve the task. This is exactly what I looked for.

Thanks for the video.
Could you explain the 'p-value' to me?
My specification (WJEC) says:
The p-value is the probability that the observed result or a more
extreme one will occur under the null hypothesis H0.
For uniformity, interpretations of a p-value should be along the
following lines:
p < 0·01; there is very strong evidence for rejecting H0.
0·01 < p < 0·05; there is strong evidence for rejecting H0.
p > 0·05; there is insufficient evidence for rejecting H0.

What does this mean? Thank you.

[gravinboginagis]

Can I just ask why you go with P(X<=2)

[bluejimmy]

Can we use a z table for this? My book only has problems with z table when it comes to proportion hypothesis testing. Is this problem not normally distributed? Thanks.

[arijitchakravarty]

Wonderful! Thank you - but how do you punch into the calculator x is less than or equal to 2?

[laurenlam]

So, if theoretically, the P(X<=2) value was less than 0.05 (the significance level), we would accept the null hypothesis?

Also, does is this true all for binomial hypothesis tests?

@TLMaths How do I know when to use 1 -

[OtterFan]

I write this "There is insufficient evidence to reject H0" is that right?
