The central limit theoremtells us that no matter what distribution things have, the sampling distribution tends to be normal if the sample is large enough (n > 30). However, to be consistent, normality can be checked by visual inspection [normal plots (histogram),Q-Q plot(quantile-quantile ...
An approximate confidence interval for a population mean can be constructed for random variables that are not normally distributed in the population, relying on the central limit theorem, if the sample sizes and counts are big enough. The formulae are identical to the case above (where the ...
When x = π, the Fourier series converges to 0, which is the half-sum of the left- and right-limit of f at x = π. This is a particular instance of the Dirichlet theorem for Fourier series. Example 2: Fourier's motivation[]
With large enough sample sizes (n > 30) the violation of the normality assumption should not cause major problems (central limit theorem). This implies that we can ignore the distribution of the data and use parametric tests. However, to be consistent, we can use Shapiro-Wilk’s significance...

so it defies Noether's theorem, the most fundamental and beautiful cornerstone of physics. Symmetry and conservation are two sides of the same coin. "All things are transformations of one thing, without gain or loss," as my childhood tutor put it. "If A can become B, then B can ...
