Binomial hypothesis testing - as level s1

I am really confused about binomial hypothesis testing, with critical regions and values and all that. I can't seem to get my head around it! Can anyone go through it for me?

Thank you!

Sure, what do you need help with?
If you set it all out correctly, it should be fine.
I'm revising for S1 too btw.

Okay, so in two tailed tests you need to halve the significance level as you need to test both ends of the distribution.

You must test/ show both the upper and lower ends of the distribution.

Then you find the critical region, and the critical value is the number that just fits the critical region I.e. the highest or lowest value.

You need to state p, X, the null and alternative hypotheses.

If the value you are testing is in the critical region, you reject h0.

Hypothesis testing isn't in S1...

It is, if you have OCR MEI as an exam board.

okay, so aren't there two critical regions? as we're doing upper and lower ends?
which critical region does the value have to lie in?
