A normal distribution has a mean of p = 60 and a standard deviation of o = 12. 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. M = 64 for n = 4 scores: z= 0.67 V ,which is atypical V value. M = 64 for n = 9 scores: 2: 1.00 V ,which is atypical V value. M = 69 for n = 4 scores: 2 = V , which is V value. M = 69 for n = 9 scores: 2 = V , which is V value. M = 66 for n = 16 scores: 2: 2.00 V ,which is atypical V value. M = 66 for n = 36 scores: 2 = 3.00 V , which is an extreme V value. M = 54 for n = 4 scores: 2 = V , which is V value. M = 54 for n = 36 scores: Z = , which is value
