I got this too
I got 173 for h value as well.
For the P(AnB) I got 0.33, what did people get for coding, I don't really know how to do that.

Most of my friends got 0.33 too
For coding The standard deviation only changes if you x/divide but isnt affected by adding or subtracting
for mean i think you just solve..
guys if anyone knows who arsey is he does markschemes, i believe they get released at midnight :smile: please post the link to the unofficial mark scheme if he uploads one :smile:

I think I got 57 for the mean, I forgot what I got for the standard deviation though...

Answer was 172.96 for 7c
Answer was independant because both 0.33 for last part of question 8
The height in the first question was 7.5cm
The mean was 57 with some decimal places

I did the standard deviation wrong, I squared the 1.4 before substituting in X, you should have just left it then ignored the -20
