What did you guys get for the revenue one for the governemt for the cars?
did you do 25/80 x 15000000 or whatever?
the x by 1000?
I guessed by doing 25/80 * 2.5million, then for some reason I multiplied by 1000 to get 781 million pounds :P

GUESSED totally.
4. Re: OCR MEI Statistics 1 (S1)
i stupidly miswrote the X~B thing wrong, but i got the right answer i hope with all the right workings out, would i lose a mark for doing that?

Also does the histogram have to start from where your data starts, or can it start from 0?

And would i lose a mark for only labelling it 'frequency density' without a unit?

I ****ed most of the paper up anyway, but i want to know if i've got 3 more marks to scrape a B
5. Re: OCR MEI Statistics 1 (S1)
Also what did you guys get for the two combinations question?

480?
then 480/3003 which cancels?

oh **** do you think i'll drop a mark not for cancelling? also wasn't it 840 not 480? or have i screwed up loads x
11. Re: OCR MEI Statistics 1 (S1)
did ppl get 8 for expectation and something like 1.6 for variance.. cant remember exactly (for the probability distribution of the coins)

Oh infact, it was 5 questions from section A and 9 from section B, 14 is right x
15. Re: OCR MEI Statistics 1 (S1)
Yes it was 840 just forgot the figures. Seem quite happy about the exam just made a mistake with the standard deviation and mean, must of been calculator issue. Would I still get follow through marks for this and the outlier question?
16. Re: OCR MEI Statistics 1 (S1)
