    Yeah, the bar widths were very cramped. And they didn't really give much graph space to draw a larger scale. My y scale went up in 2's and the X in 20's

    Could you start at 10 for the histogram? Or did we have to start at 0.

    YOUR BOI BOB6969 (hopefully correct) answers

    1i) IQR = 4 (or 4.15 depending on method) Median = 29
    ii) No outliers

    2i) 0.512
    ii) 0.16
    iii) 0.66 i think

    3i) 120
    ii) 1/60
    iii) 1/60
    iv) 0.1

    4i) 50k = 60 so k is 1.2
    ii) E(X) = 2.74 Var(X) = 1.232

    5i) 0.21
    ii) venn diagram
    iii) 0.241

    6i) mean = 70.19 s.d. = 36.90
    ii) 15.7%
    iii) histogram drawing
    iv) positive skew
    v) 20.2%
    vi) men shoes had smaller mean and lower spread

    7ai) 0.1423
    B) 0.2108
    C) 1.6
    ii) p=0.1 h1, p<0.1
    iii) Not writing it out
    iv) don't reject as 5.3% > 5% so insufficient evidence

    I think that the x-axis must start from 0.

    You may lose an answer mark depending on how cruel the mark scheme is and how many marks the question was worth!
    I put a fraction for the variance.

    I just looked it up and apparently you can start at 10. If the lowest value is not 0, then you don't have to start at 0.
