    I did that too. You can leave it as a fraction or decimal can't you?
    I think so. I've just seen in a past paper before mark down 1 if not put as rounded decimal but I think it's ok

    Hm - never sure with stats. Section A was easy, section B was a little more challenging. Half my class got accept H1 for both and the other half got accept H0 then accept H1 - anyone know for sure? It looked as if it would be accept H1 for 1%, but anyone know for certain?

    For the last question I just did 6/20 * 5/19 which gave me 3/38.

    Quite sure this is correct because the third chocolate doesn't matter

    I did that. You don't get marked down if you leave your answer as a fraction do you?
    I don't think so

    I got Reject H1 because it was outside the significance level ?

    your answer would be getting other chocolate exactly after 2 cherries?

    because it asked at least 2 cherries before other chocolates that he likes..
    Let cherries be C and others be B
    the possibilities of not getting at least 2 cherries be4 other chocolate would be
    CB
    BC
    BB
    i did 1- P(CB+BC+BB)
    I am probably wrong ..

    I think so too, as it said 'more than 2 attempts' to get one he liked (a non-cherry).

    Reject H1 in first question as it is outside sig level but reject H0 in the second part when its 5% sig because its smaller than 5% therefore there is sufficient evidence to suggest the new drug works.

    Not really sure whether what I wrote for the justification was right - I just said that it was important to be really accurate with the drug as it was life saving?
