Using the Central Limit Theorem, it is found that the shape of the sampling distribution of the sample mean wingspan is normal.

<h3>What is the Central Limit Theorem?</h3>

It states that the sampling distribution of sample means of size n, from a normally distributed population with mean \mu and standard deviation \sigma, is normally distributed with mean \mu and standard error s = \frac{\sigma}{\sqrt{n}}.

Hence, applying the <em>Central Limit Theorem</em> in this problem, the shape of the sampling distribution of the sample mean wingspan is normal.
