Question: A population has a mean of µ = 80 and a standard deviation of σ = 10.

(a) If you selected a random sample of n = 4 scores from this population, how much error would you expect between the sample mean and the population mean?

(b) If you selected a random sample of n = 25 scores, how much error would you expect between the sample mean and the population mean?

(c) How much error would you expect for a sample of n = 100 scores
