i don't understand how you guys got 9 haha please explain
because there are 30 scores right, and the 15th and 16th numbers form the median, so the median is 11, which leaves 14 on each side, and then the 7th and 8th numbers from the median make Q1 and Q3 which are (7 and 8) and (18 and 18) so yeahhh, im just confused!
The question asked only for the female scores.
So there's 14 scores total.

This is definitely right. I knew it as soon as i left the exam room. Did it on maths online and all. I think you would still get one mark though, if u didnt do this, right?
Oh well i don't know my final answer was 10165 km (nearest km)

I put the 1/2^10 because it was the probability of getting a tail on the 10th toss aka 1/10x1/10x1/10x1/10x1/10x1/10x1/10x1/10x1/10x1/10... i hope im right ahah

Answers ranged from 159-162, depends on if you used the rounded figure from the previous question Or used the un rounded answer, either way the answer should be right

How did you get your answer?
I added 180+31
=211degrees

6 is d
if you let a = 1
and x = 0
you get a y intercept of 1, works for every other value greater than 1
so its D

Was there any need to draw a tree diagram today or convert currency?

I can't remember but they seemed non-existent in this test, as well as having to differentiate from population standard deviation and sample standard deviation.

You had to use alternate angles to find the 55 degree angle, and the Sine Rule to Find ACB then add the ACD, 55 and 180...I got 261

I got 9
Median = 17 (so then there's 7 scores on either side)
Lower quartile = 11 (Middle of lower than median scores is 11 with 3 scores on either side)
Upper quartile = 20 (Middle of upper scores from median is 20 with 3 scores on either side)
+1, this is correct
