How do you use the Percentage Points table in the S1 booklet?
At the back there is this table:, how and when would one use it?

Well, exactly how it says. If you want to find the number z such that P(Z > z) = 0.3, you can look it up. It's rarely used in S1, but in S2 you often have to find the number a such that P(X < a) = 0.05, where X is a particular normal distribution, and that's where you'd use this table.
