FIGURE 6.3 The central limit theorem in action: the distribution of sample means

$\bar{x}$ from a strongly non-Normal population becomes more Normal as the sample size increases. (a) The distribution of one observation. (b) The distribution of

$\bar{x}$ for two observations. (c) The distribution of

$\bar{x}$ for 10 observations. (d) The distribution of

$\bar{x}$ for 25 observations.
