Question

We have a normally distributed population of scores with μ = 25 and σ = 5. We have drawn a large number of random samples with a particular sample size of n = 10 from this population.

We want to know what the probability that a sample mean will be equal to or greater than 23.

First, what is the z-score for our sample mean of interest, 23?
