@bremen79 You can also use “empirical Berry Esseen bounds” to get both finite sample validity and asymptotic efficiency (matching the optimal CLT-based width in the limit)

Efficient Concentration with Gaussian Approximation

Concentration inequalities for the sample mean, like those due to Bernstein and Hoeffding, are valid for any sample size but overly conservative, yielding confidence intervals that are...
