2 marks. The actual number rounded to 260.3 and if they are picky they may not give you the mark. But who knows? You may get a benefit of the doubt mark.

Can someone answer some questions I have about the paper? the Actual paper: https://drive.google.com/file/d/0B3xSC6XqSy7kMGhaRHh2MHlnaDQ/view

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?

For this question you will lose 1 marks for getting the answer wrong. You will gain all method marks for using this value as carry through but as fas as I understand the marking system you will lose any final answer 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?

As far as I know, you don't get marks for just writing the formula, you will have been required to put values in the formula and generate some sort of answer... Not entirely sure about this one, possibly 1 marks in total max.

For question 5a, I got the width right but height wrong. Will this only get me 1/3 marks?

You will get 1 mark for the answer.

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?

A lot of dispute about this answer, many past papers have suggested that since the median and mean is approximately equal a normal distribution is suffice. I personally put that it was fine, but many people are stating that due to the negative skewness it is inappropriate. I honestly believe that from past paper answers of similar questions your answer will be correct, but don't hold my word for it.

Hope this helps. :smile:

That is not right, you are assuming that they both play the same number.
You have to draw a sample space, there might be a shortcut but there wasn't much time to look for one.

Use last year's grade boundaries. Not 100% accurate but should give you a rough idea.

Last year it was

C1 - 63
C2 - 59
S1- 59

I Think I would get an A because the c2 would boost my S1. IDK ;( I want an A so bad. I just hope S1 boundaries are not higher than 59 so I will have a bit more UMS
