Use the Standard Normal Curve Table to answer this question for the following z-scores: 

a) -1.12

b) 1.46

c) 1.68

Draw a diagram (as neatly as possible) for each z-score and label all the areas. Clearly mention the proportion of area in the three cases; 1) the area below the z-score, 2) the area between the z-score and the mean, and 3) the area beyond the z-score. (You will draw one diagram for each z-score and shade all the three areas in one diagram. This means you will in all draw 3 diagrams for this question).
