Yes but the gradient was negative (ie. the line sloped downwards not upwards). Sorry if my explanation is hard to understand!

you got 24 iv wrong it asked for the width not the length. The width was 240mm.
They will accept qualatative instead of categorical aswell.
also q28i you are right but lost a mark cause you didnt say unless you round it down, because it will reach 0 when eventually rounded down.
24 ci was 59 degrees
25a iii you and your teacher are wrong you did a systematic sample instead of a stratified sample.

you probs got 85/100 your shit

Br8, stop hating.

So, for q24 a) I stupidly didn't look at the measurements provided and used a ruler instead (so demensions of the bathrooms were 20mm by 20mm instead of 2000) . Because I did it for all 4 parts of the question, do you think they will let it be a carry-on error?
