Some resources to help understand the normal approximation to a binomial distribution.
- A Powerpoint investigating when a Binomial distribution is close to a normal distribution, and also a video commentary of the Powerpoint.
We find that if the sample size is too small (or too skewed) then the normal approximation is good. Specifically, we want np>5 and nq>5.
- A couple of worked solutions to example problems, in video form
