Not sure to be honest. I don't think I've read too many mark schemes, but I reckon you'll get 5 marks.
3. Thanks
4. sorry i cnat be bothered to read veeryones views its just too long lol

i think the first six questions were relatively easy..and if u revised rpoperly this wud be da case

question seven thre me back a bit

did anyone use the possion for q.7 i used x-po(7.5)

i have never seen a question on reversing in my life but i guess at leats one question had to be tricky

yes it was negative skew but i was unable to find the median..i know u diffretiate then eqaute it to 0 but i knew it was negative as i had the mean and mode values

mode<median<mean..or sumtin like dat i 4got now

ppl seemed confused with the 1st question but it was ok..n=125

the continuity question was ok..39.5-50 over suware root of 50 or sum numbner i 4got

now for C4......................
5. As no one has even attempted the "typo" conundrum, there was a "that" missing from a sentence. I can't remember exactly where, but if you have time to waste, grab a paper and have a blast finding it!

6. I think i smashed this paper it was too easy. But P2 was easier.
only question i coudnt do was the sampling distribution definition.

x-Bi(20, 0.25)

Therefore (x 'greater or equal to' c) is < 1%
(x 'smaller or equal to c-1')>99%

from tables c-1=10, c=11

therefore x 'greater or equal to' 11 or more people who DO NOT recover!

therefore for people who DO recover.

x 'smaller or equal to 9.
Thanks for this post taintang. im sure this is correct answer.
