Arsey's Edexcel S1 S14 (UK R + IAL ) Model Answers

Here are my solutions to the UK S1 paper

(R) and IAL to follow once I get hold of those papers.

Overall I thought the first 6 were okay and the last 2 were tricky

Boundaries of the last 5 papers have been pretty consistent, so I would expect anything different for this paper

IAL Now added, seemed to be quite an easy paper. I was doing these solutions whilst watching the footy, so I am not 100% about them, lol.

Thanks a bunch for the quick upload! Is that table (one going 70, 80, etc) UMS or Percentage or Grade boundaries?

i got 75.5 for 6b instead of 75.4, would this be ok? i also used this to calculate a skew of 0.074...obviously this is a large difference from the 0.0845
also for 8c i got 0.24(this is wrong) would i get the mark if i showed they were independent using this value?

Hello. For the last question, I got the probability of A wrong, but then went on to answer all the remaining questions. How many maximum marks do you reckon I would lose?
Thank you in advance. :smile:

Thanks so much as always.
I couldn't work out what on Earth was going on for most of the last two questions but seem to have got them. At the very least, method marks. Should be okay.
