    Oh yeah, thinking back you're right. Well I think that's sorted then, mustn't matter.



    I'm glad someone else was left thinking that, I thought I'd gotten something wrong
    Normally it's 3 or even 2 marks ... one of the marks must be for putting the %

    for some willy old specs they give 5 marks for confidence interval so i'm not really concern about that. on the other hand 4 marks for the new variance question seems odd to me.

    does anyone reckon they wouldnt accept converting % to decimals from the start and doing that for the final answer i.e 0.195 instead of 19.5%?

    Aha are you trying to reignite this % mystery?
    It said mu% in the q so it normally gives you leeway on the answer because it would be like writing 19.8%% iygm

    Thinking back on past papers that's very true. Everything just intensifies in the exam lol

    Can someone else also confirm how many marks Q4 part (a) was?
    I heard few different answers (about the amount of marks for this question) so I dont know which one it is.

    Part (a) was about difference in E being greater than 2.
    P(I e1-e2 I > 2)

    No it wouldn't...the numbers you write are the limits of the confidence interval. They don't have a % already attached on them

    EDIT: oh I see what you mean...yeah maybe but they could be ********s about it

    For the Binomial (8 marks) and Poisson (6 marks) tests when working out degrees of freedom I forgot to subtract the initial restriction (v-1 - further restrictions) on both, how many marks do you think that will have lost me? :/

    I don't mind doing one, I'll see if nobody else has done one and if so, then I'll pitch in. I think someone else might be doing one, though.
