Why is 1bii 24/100? I put 24/120 :frown:


I think that was is the wrong one

So I was correct? :smile:

For 12b, how many marks will this be 'there is very weak positive correlation and as one judges mark increases the other one does slightly and vice versa'?


Also for the one about Netto do you think 1890 will definitely get the mark?

I cba checking

Urmmm... Maybe a mark? I think it was too close to 0 to have a correlation. .

If that's the answer stated there
For question 14) b) can you not say that the median is in that class but since they do not have the less than or equal sign with 350,000 it cannot be the median
Also for 4)b) can i not say that the total of fx will be higher but x will remain the same and so it increases the mean

For 13) a) I put that the mean was 54, and the standard deviation was 9. How many marks out of the 3 do you think I will get, and can I possibly get all the marks on the next question based on follow through answers?

For 1) b) ii) The answer should be 24/120 because the total number of people are /120 not /100
I am sorry i am a bit new to this, but may i know where i can find the actual mark scheme to this exam paper ? I am getting really worried. I think I failed it ? Thanks for the help... When I say actual mark scheme, i mean the mark scheme everyone is talking about?

I beg to differ, in the two way table, it said the total 100...

I calculated the gradient using the y2-y1 divided by x2-x1 method I got 1.04 :s-smilie:
On the RDA% question... Instead of the difference was 62% I said the standard curry had about 3x as many saturates as the light curry along with the first point on the ms - wud that be in the accept column do you think?
