haha ;) cricket insect
nah it was about a scientist measuring the relationship between temperature and amount of cricket chirps...gave us a box plot of temperatures over 20 days and told us there were 684 cricket chirps in total; gave mean temperature...
and then the least squares regression line with (where y=chirps and x=temp)

blah di blah (a lot of information my poor brain!)

then we had to figure out amount of chirps expected on a 19C day :P i was like um yeh well NOPE

how tf were we supposed to answer that cricket question though...and apparently standard had the same one?? ugh I'm so mad at my school for never teaching us a thing about regression lines, everyone in my year was absolutely stumped with that question and I'm mad at myself for not doing enough past papers lol

I heard there was a 23 mark cross over with the standard paper. It would be interesting to know which questions.

yeah I heard something similar. I think it must've been the crickets one, the annuities one and the venn diagrams/probability questions. haven't done a venn diagram since like year 10 so had a mini heart attack when I saw that one lol

What did everyone think of the multiple choice? I thought there were a few weird ones.

I thought 8 and 10 were very hard, I was basically making an educated guess on both of them.
