For a sample distribution of scores, X=36 corresponds to a z-score of z=1.25, and X=42
corresponds to a z-score of z=0.75. What are the values for the mean and standard deviation for
the distribution? (Hint: sketch a distribution and locate each of the z-score positions.) Show all
work including a sketch of the distribution labelling the z - scores on the distribution. Write
down all formulas used. Show all hand calculations necessary to solve the problem. Answers
without hand calculations will receive no credit.
