Sampling and normal distribution hhmi answers
WebThe sampling distribution of sample means can be described by its shape, center, and spread, just like any of the other distributions we have worked with. The shape of our sampling distribution is normal: a bell-shaped curve with a single peak and two tails extending symmetrically in either direction, just like what we saw in previous chapters.

WebSeveral answers mention the possibility of using the central limit theorem to approximate the normal distribution as an average of uniform random variables. This is not generally recommended. Arguments presented, such as matching the mean 0 and variance 1, and considerations of support of the distribution are not convincing.
