checked it again. both the last two questions are meant to be insignificant. the chi test was 8.039 or something amongst them lines i really hope I picked up the method marks.
yep i sed that n is large, p is small and np is not large (i.e. less than or equal to 10), the exact distrubution was just X~B(5000,0.0001), the mean of the poisson was 0.5.

This, but not np is not large (I hope I wrote enough to secure the marks).
Either way, I can't understand how you can talk about an exam after it's happened... always makes me feel awkward and crappy for knowing I've got questions wrong... and a chance for people to boast about them getting questions correct

Why are you posting the same thing in different threads?
Awh **** this paper was so boring, I nearly fell asleep. On question 1 can't even remember what it was, but I think it was pretty straight forward, and I think i rejected H0 though not entirely sure.
I remember accepting H0 once and rejecting H0 all the other times - I think.
I messed up the question were it said why is poission suitable by saying all the crap about random, independant and unifrom rate.
What did people get for the mean and variance on question 2.
That last question on 3 threw me but the whole of question 4 was pretty nice /
