Abstract: The Kolmogorov distances between a symmetric hypergeometric law with standard deviation $ \sigma $ and its usual normal approximations are computed and shown to be less than $ 1/(\sqrt {8\pi }\,\sigma )$, with the order $ 1/\sigma $ and the constant $ 1/\sqrt {8\pi }$ being optimal. The results of Hipp and Mattner (2007) for symmetric binomial laws are obtained as special cases.

Connections to Berry-Esseen type results in more general situations concerning sums of simple random samples or Bernoulli convolutions are explained.

Auxiliary results of independent interest include rather sharp normal distribution function inequalities, a simple identifiability result for hypergeometric laws, and some remarks related to Lévy's concentration-variance inequality.
