    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

    I'm glad someone else was left thinking that, I thought I'd gotten something wrong
    Nah, happens all the time in S3. You get answers that are 1 line for 8 marks.

    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.

    For the binomial question, did anybody else round 0.405 to 0.40 rather than 0.41? Because 0.41 would have made the total expected frequency 50.01 rather than 50?
