Question 1136579: (For this question, consider z values greater than 3 as atypical).
A population of scores forms a normal distribution with a mean of μ = 80 and σ =20. Is it atypical to get a mean of 84 in a sample of n=4 scores?

This z score is not larger than z = 3, so it is not atypical (aka unusual) to have a sample of 4 scores lead to a sample mean of 84
