AS AQA Mathematics Statistics 1B MS1B June 2014

can someone upload the official mark scheme please? i've completely messed up the last question,i really want to know if i've got the other questions correct

This exam was an average paper overall, however I made 2 mistakes. Firstly question 1, can anyone remember there answers for the 2 standard deviations, also question 6 i made a mistake I think as when I put x in the regression line it didn't fit the table, my regression line was y=10.75-0.00085x can anyone remember there's please?

I got y to be abou 14.9 ish or something like that

I was pleasantly surprised by that paper. The questions were well balanced and hopefully it'll make up for my complete mess up on core 2

Also, as someone has requested, feel free to assemble an unofficial mark scheme. I can't remember any of the answers I wrote down so I'm useless

imo it was a better paper than most past papers i've done. only realised towards the end i completely missed one of the questions.. the question where you had to find the probability where it doesn't equal X which was 1.

easiest mark you'll ever pick up lol

How do you think will the grade boundaries be? What will be the boundary for an A?

For the insurance probability question, didnt you have to subtract the probability of getting 3 or above from 2 to find the exact probability of getting a 2??

lol did you manage to put the right answer in
