Hi people, quick question that is very unlikely to show up on the exam anyway:

When using a normal approximation to a binomial distribution, it seems to be pretty standard to make a continuity correction, see:

(These are just the first few results in Google)

Yet this is not mentioned at all in my textbook (Cambridge), and I can't find reference to it in the study design. Do you know if we would be expected to just ignore this step (and get a worse approximation) and would we be likely to lose marks for using it?
