Question

1. What is the mean of the sample means? (2 points)
2. What is the standard deviation of the sample means? (2 points)
I am confused as to what these are asking?

Answer 1

The question relates to the Central Limit Theorem.
1.The mean of the sample means is the mean of the parent population.
2. The standard deviation of the sample means is given by
\[\frac{\sigma}{\sqrt{n}}\]
where sigma is the standard deviation of the parent population and n is the sample size.
