A data scientist is investigating the duration of sessions, $S$, on a new mobile application. The underlying distribution of $S$ is heavily skewed towards shorter sessions and is certainly not normal, though it possesses a finite mean $\mu$ and a finite standard deviation $\sigma$. For a large random sample of $n$ sessions, the scientist utilizes the Central Limit Theorem to approximate the distribution of the sample mean session duration, $\bar{S}$.
