Do you think I will lose 1 or 2 for giving answer in degrees rather than radians

most likely 1.

Although it'll be pretty stupid. As it is still correct. I have seen in previous ms where they award marks in some questions even tho it asked for radians.

1 Mark. You'll only lost the answer mark I would think. Can't do calculus in radians but if you got to the correct solving form then I reckon you would get 2/3

Quick question...

For a sampling distribution of the median (7 marks)

Say I got all the probabilities correct

But took (10,20,10) to be a median of 20 so got the final probabilities wrong

How many marks lost?
