# Question: A normal distribution has a mean of 60

A normal distribution has a mean of µ = 60 and a standard deviation of σ = 18. For each of the following samples, compute the z-score for the sample mean and determine whether the sample mean is a typical, representative value or an extreme value for a sample of this size.

a. µ = 67 for n = 4 scores

b. µ = 67 for n = 36 scores

a. µ = 67 for n = 4 scores

b. µ = 67 for n = 36 scores
