Final answer:
The shape of the sampling distribution of the sample mean wingspan is a normal distribution.
Step-by-step explanation:
The shape of the sampling distribution of the sample mean wingspan will be a) Normal distribution.
The normal distribution is a bell-shaped curve that is symmetric about the mean. It is used to model many natural phenomena and is commonly observed in sampling distributions.
Examples of normal distributions include a distribution of heights in a population or the distribution of test scores in a class.
