Glad to know I'm not alone haha! I was dead confused aswell but when I read the preamble at the top it kinda makes sense (like the upper price prob is included within the lower price prob )
And I also couldnt find out the third PMCC! it gave you sxy and sxx, but i couldnt find syy anywhere!
Yeaah it does make sense! I think syy was just one of the values at the top, can't completely remember though.
OMG, are you talking about edexcel? the venn diagram was freaky!! but i can't remember any questions with jewellery, dave or bowling!! Ohhh and for the 1st Q, shh was -22400?? something like that?
Unlucky, syy was at the top of the question, syy = 5880. I know how you feel about that mistake, I have made silly mistakes on the FP1 paper I did today.
I remember trying one of the ones included at the top, and it kept giving me a massive number much bigger than 1, it had me so annoyed and i ran out of time in the end
What did people put for the last couple of questions for 4. Like calculate the least squares regression line ? I got y = 0.6 + x But I'm not sure I'm right because I just used a random formula from the booklet because I haven't come across anything like it before :/
yh i got that hopefully that's right *fingers crossed* i was thinking i was the only one who go tthat answer
C1 in January? 3 UMS off a B. I knew I could do so much better so I resat C1 on Monday (did it before C2 on the same day) but found this resit much harder. So, could've done better, could've done worse but we'll just have to see in August
That's a really good result
And you know what....
I bet you will do well

I got 28.05 something like that is it the jewellery one where u had to estimate the # of people or something can't really remember what it was..
so i rounded it off since u cannot have 28.05 jewelleries or something it context of the question .. somebody help me what the question was i think it was binomial or random.
correlation between x and y was 0.987, so they were vertually the same at each value.
to comment on a and b: gradient was 1 was pefect corelation which didnt change the value of x. a was like 0.4 so x was only 0.4 bigger than y. something like that

The value for a was actually 0.467 or something close
I don't know where the 0.6 is coming from
And the b value was 1.00
So y=0.467ish+1.00x
