A population has a mean of = 80 and a standard deviation of = 20.

Question:

A population has a mean of µ = 80 and a standard deviation of µ = 20.

a. Would a score of X = 70 be considered an extreme value (out in the tail) in this sample?

b. If the standard deviation were µ = 5, would a score of X = 70 be considered an extreme value?
