Sampling and statistics
We will work in pairs.
Generators: We shall perform sampling from two random distribution the normal distribution and a uniform distribution over some range .
![{\displaystyle [a,b]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/9c4b788fc5c637e26ee98b45f89a5c08c85f7935)
Statisticians: Take your friend's generated data, and for each set of data compute the sample mean and the sample variance .
