Ede4ka [16]

Answer:

The sampling distribution of X, for a sample of size 16, will be approximately normal with mean 2 mm and standard deviation 0.01 mm.

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For the population:

Mean 2 mm, standard deviation 0.04 mm

Describe the sampling distribution of X (for a sample of size 16).

Sample of size 16 means that n = 16

By the Central Limit Theorem, approximately normal with mean 2 and standard deviation s = \frac{0.04}{\sqrt{16}} = 0.01
