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
and standard deviation
, is normally distributed with mean
and standard error
.
Hence, applying the <em>Central Limit Theorem</em> in this problem, the shape of the sampling distribution of the sample mean wingspan is normal.
