Statistics Question

Question

If random samples, each with n = 9 scores, are selected from a normal population with μ = 80 and σ = 18, and the mean is calculated for each sample, then the average of all the sample means would be the following.

Answer 1

To calculate the sample mean from population mean,

x̄ = μ(n/(n-1)) because of the degree of freedom

I believe this is the question?

Answer 2

The Central Limit states that the sampling distribution of the sample means from a normal population is normally distributed with the average of all the sample means being equal to the population mean, which in this case would be 80.
