Why do they have to scan in???? I never knew this before and I never use black ink in exams
Because the examiners are lazy :p:...Joking, scanning is a more accurate way of marking but they are also marked again by examiners for any faults found and this process can be repeated several times.

I'd recommend doing all of them from 2001-2010. I did notice that some of the earlier ones do have some slightly more tricky questions than the newer ones.

This is going back to an earlier q about the probability of incorrectly rejecting H0..I think it means this...
When you reject H0 you are doing it because new evidence suggests it to be wrong. However, there is a probability (5% so whatever this equates to) that H0 is still right.
I think that's why in more important tests, ie medical, the critical region is a lot smaller and therefore there is a much smaller chance of incorrectly rejecting what I'd actually a true hypothesis
Hope this makes sense

If you can handle those from 01-10 and solomon's very well, then there shouldn't be any problem. How did you find the solomon's?

the solomon papers were very easy - very unusual for a solomon set of papers

ah yes - I was worried about the same thing. However, once I did all the past papers I managed to learn all the definitions through getting them completely wrong on the first two papers lol

Same for me, once I get these I should get close to full marks (as long as I don't make silly mistakes )

If you're aiming for >90%, make sure you do learn the definitions. I lost 2 raw marks in my S2 exam and managed to drop 5-6 UMS marks.

The variable T Distributed by N(8, 4), why does P(T = 5) = 0?
Isn't it meant to be P(4.5 < T < 5.5)?
