Find the conditional distribution of happiness by marital status for the data in Table 9. Then draw a bar graph that represents the conditional distribution of happiness by marital status.

Approach First, compute the relative frequency for happiness, given that the individual is "married." Then compute the relative frequency for happiness, given that the individual is "widowed," and so on. For each marital status, draw three bars side by side. The horizontal axis represents marital status, and the vertical axis represents the relative frequency of the level of happiness.
