For a population with a mean of μ 80 and a standard

deviation of 12, find the z-score corresponding to

each of the following samples.

a. M 83 for a sample of n 4 scores

b. M 83 for a sample of n 16 scores

c. M 83 for a sample of n 36 scores

A population forms a normal distribution with a mean

of μ 80 and a standard deviation of 15. 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. M 84 for n 9 scores

b. M 84 for n 100 scores
