Question

Unit test

Answer 1

Using the Central Limit Theorem, it is found that none of the samples satisfy the normal condition.

What does the Central Limit Theorem state?

It states that the sampling distribution of sample means of size n has standard deviation $s = \frac{\sigma}{\sqrt{n}}$, as long as at least one of these following conditions is respected.

• The underlying distribution is normal.

• The sample size is greater than 30.

In this problem, the underlying distributions are skewed, and both sample sizes are less than 30, hence none of the samples satisfy the normal condition.
