Hi,

I'm sitting S1 on the 5th with the exam board OCR.

I'm struggling to understand hypthosis testing and was wondering if there was any online sites that could help me or books or anything really?

I can set the null and alternative hypthoses but after that I'm clueless. I get confused with the books and not sure what I'm to minus from 1 or if I have to at all and if I get the right answer I'm not sure what I should write in my conclusion and what to accept or reject.

I've tried all the A2 books with hypothesis testing in but they just go over my head.

Any suggestions?
