....No. My upper quartile was 210 and interquartile was 70

bingo....you got that right !

....No. My upper quartile was 210 and interquartile was 70

....No. My upper quartile was 210 and interquartile was 70

hmm well thats what i am confused abt in many mark schemes if you get say 7.25 they take it to be 7 while in tohers they take the one between 7th and 8th so i am hoping all thsoe are right

The number of samples was odd. 27 to be exact. So for the upper quartile it's 3/4* (27+1) = 21th value, which I'm sure was 210.

I hope my stupidity didn't get the better of me, otherwise, as I said, CIE was trying to make amends after that P3 paper by giving us this one.
Thanks btw.

i messed permutations nd cudnt calculate k cause i m always tooo pressurized by time in stats.....what ws summation x^2 , it ws q 2 i think.....man u need TIME in permutations! even if it wasnt long, u still need time for thinking out a strategy !!!

It was a 5 digit number, no decimals, 65 or 63 thousand something. I don't remember really.

you need for the question to click, it can either take 10 seconds or maybe even ages...

it was 63000 cause u nedd three significant so it was 63700

low threshold my friend cause everyon e even here except perhaps little cloud and few others messed something up

Exactly.
The sum was pretty similar to those committee questions, except this time they used trees.

Yeah. Somehow my brain seems to have wiped that answer out.
