    Do you reckon we could pick up maybe 4/9 marks for Q7 if we calculated the mean C.I? We would've had to find s/root(n) at least - up until there it would've been correct. I mean that would be marks for subtracting the mean and dividing by the correct t-critical values. Sneaky buggers.

    I would have thought that maybe 4-5 of the marks would be for finding the mean & s.d, that's half the solution after all. So we could still get A* if we made no other mistakes, not sure if I did or not.
    I suspect we'd get 4/9. Which is annoying because now we're capped at 70/75...

    A couple of people have had 0.68 stored in their calculator - what was this for? I recognise most/all of the other numbers but not that one.
    Finding that value in the table for test A I think.

    Okay but did anyone else not reject the null hypothesis for like all of the tests except one? Actually I can't even remember if I had one where I did reject it.

    Yeah I think only one or two were significant. For most you accepted the null hypothesis.

    Oh, that would be it. I gave my answer to 4dp (a habit I've got into with a lot of S1-3 tables using 4dp) - do you think I'll lose marks for the extra accuracy? Did the question ask for 2dp, like the other values in the table?

    Now that the papers out: http://www.thestudentroom.co.uk/show...2#post66502982 Post 1315. Does anyone have realistic grade boundary predictions and is anyone up for making and unofficial mark scheme as there is none for stats papers...

    How long do you think it would take to self-study it then?

    By the way, do you or anyone here have the books for S4, D1 or D2 by any chance?

    I want to study them in my gap year, but I rather get a second hand book for a cheaper price.
