Hey mate could you just answer some questions please. For question 3a, I wrote sum of x squared as 958.88 as opposed to the actual 985.88, then carried on with the calculation as so. Will I lose all 3 marks for this error or will I get some marks?
For 4b, I wrote independent so P(B AND D)= P(B) x P(D). Will this get me one mark?
For 4di and 4dii, will I get any marks for writing out the formula , so for I 4di wrote that is is equal to P(D AND R AND B) divided by P(R AND B) and for 4dii I wrote that it is equal to P(D AND R AND NOT B) divided by P(R AND NOT B). Will I get any marks for laying these formulas out?
For question 5a, I got the width right but height wrong. Will this only get me 1/3 marks?
For 5e I said that it may be a good decision as the median and mean are quite similar, will this get me any marks?

Thanks mate<3
ahhh I have no clue about marks won and lost.
What I can advise you to do is look for past papers with similar questions and see how the mark scheme awarded marks for them.
