ok so for the one where tails has been tossed 9 times, what it the probablity of it being thrown a tenth toss, did you all put B (1/2). Because i think thats the answer. Its different than them saying what is the probability of throwing tails 10 times in a row. (which is 1/2^10). Because that throw itself solely has a probablility of 1/2. Do you all agree?
yep, i put 50% AKA B.

This is pretty much what i have except for 7 i put C negatively skewed because the mean was low idk probably a bad guess

I put C too. What did everyone else get for 7??

For question 7, the mean was 155. Therefore data was leaning to the left, meaning it is positiveley skewed.



i hope. lol.

damn, i think i measured the lenght of it instead of the width. Got mixed up. :D
I think you were supposed to use the floor plan to get the answer because the question said "use the floor plan to determine the width" so if you check the floor plan you can see 90mm seems logical for the width of the windows hence that was my answer.

Eh i think you will find 1: C is a pyramid not a prism. Other than that we seem to have very similar answers

MC.

1D, 2A, 3B, 4C, 5B, 6D, 7B, 8D, 9C, 10B(Don't know), 11D, 12A, 13A, 14B, 15B, 16D, 17C, 18B(Don't know), 19C(Don't know), 20A, 21A, 22A

In regards to Q24 (a) (iv) Windows width: I had answered 1800mm. I understand the confusion over what's the width or what's the length but thinking logically, measuring such a small distance is quite a strange question.

Found it pretty easy compared to recent papers, though I made a few really silly mistakes ><.

Can someone please post a link on here when/if they find solutions to the paper?
Thanks :)
My answers-
1 D, 2A, 3B, 4C, 5B, 6C (it's not D as the y intercept is greater than 0 thus the formula would be a^x + 1 or w.e.), 7C(silly mistake), 8D, 9C, 10A, 11D(silly mistake once again :( ), 12A, 13A, 14B, 15B, 16D, 17C, 18A, 19C, 20C, 21A, 22A.
