The wingspans of a common species of housefly are normally distributed with a mean of 15 mm and a standard deviation of 0.5 mm S

Ahat [919]

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.
