AS Edexcel S1 - (5th June 2015) Exam Thread

what question was this can't even remember it? the last 1? if so no you'd lose accuracy marks and that's it 3/6 maybe 4

What did you find hard of out interest? Maybe you're only thinking about the bits that didn't go well and overall you did okay!

70 degree done more accurately due to median being closer to 70, train station was house J I think I put?? Because it was cheaper per square meter as r was negative.I think that one was that it was unreliable because the temps were out of range?

I got the angle of 70, could be wrong

What did you get for the outside of the venn diagram? Some people got 31 and others 22.

fs man things aren't working out for me

because you know the probability of X>28 is 0.0808

and P(X>w|X>28) = 0.625

so the (X>w) part has to be 0.0505, as it has to divide by 0.0808 to give you 0.625.

so look up 1-0.0505 in the table, as it's greater than, to find 0.9495 in the table which has a z value of 1.64.

Probably explaining it badly

For the venn diagram, I stupidly thought there were only 60 people instead of 80 and wrote 2 on the outside of the venn diagram instead of 22 (which everyone else in my school did). I used the diagram for all my answers but do you think that will affect my marks because hopefully i got the inside correct. I also did 47/60 for one of my answers instead of 47/80.

What did you get for the outside of the venn diagram? Some people got 31 and others 22.

Were there 22 people not taking anything?

what was that coding question all about??

For the venn diagram, I got 31 for the number of students who didn't take biology, chemistry, or physics, did anyone else? Because the total number in the circles added up to 49 so 80-49=31?

Were there 22 people not taking anything?

I got 29.2 for the last q w - anyone else???

22



at least these are only resits, smash your important exams!

The which house was closer to the station question was trying to trick you I think, unless I got it wrong. You had to work out the price per metre squared and the cheaper house ended up being more expensive per/msquared as it was smaller, so House H was closer due to the negative correlation/inverse relationship, right? :s
