A population of values has a normal distribution with μ = 61.4 and σ = 61.1 . You intend to draw a random sample of size n = 219 . What is the mean of the distribution of sample means?

Answer 1

Hi Rose,

Part of the Central Limit Theorem states that with normally distributed data,: the mean of the distribution of sample means mu_{xbar =} mu, the population mean.

mu_xbar = 61.4

I hope this helps.
