1. A population consists of the following six scores:

9  4  6  7  10  6

a. Draw a frequency distribution graph (Do not forget to label what each axis represents) (1).

b. Compute μ and σ for the population and locate them in the above graph (3).

c. Transform each of the scores above into a z-score (3).

d. Draw a frequency distribution graph of the z-scores you computed. Did the shape of the distribution of the z-score change from the original shape of the distribution of original scores? (.5)

e. Compute the mean and standard deviation of these z-scores by hand (3).
