A population has a mean of μ = 100 and a standard deviation of σ = 10. If a single score is randomly selected from this population, how much distance, on average, should you find between the score and the population mean?
If a sample of n = 4 scores is randomly selected from this population, how close on the average should the sample mean be to the population mean?
