    how the hell did u manage to do the last question?i put more than 150ml, because the mean of 100 with standard deviation of 10 could have a maximum value of 150, so I said it should be more than 150.
    tell me how did u do that?

    i thought that was quite hard!got 100 and something(109 or 106 or maybe it was 110!) for the last question. i said apple as i ended up with 1.4 after doing an equation, which was less than the 2 i got for blackcurrant and so apple was then the closest to the mean. does that sound wrong r what!!!!!!!!for the tagging thing i got 2ooo and something as well.4 the crude and standardised thing i got two numbers that were 200 and something.i just left out the david mean thing, what was it???3 marks????thought i could afford myself that but lookin back i ain't so sure!!!for the number of pupils out of 390 who were good at spanish and french wat did u all get? i got 312 :-(
    sorry 2 any1 who hates goin over exams afterwards but its the only thing that puts my mind at ease!:-)

    Dammit- just realised that i got the standardised scores thing wrong because i'm incapable of dividing 4 by 2- i put 0.5! think i got 243 for the David's mean thing cos i thought that since it was between 225 and 255 u just needed to find 0.6 times 30 (the differnce) and add it onto 225 (which represented three....not sure if that's right tho....lost out on my A* there!
