The Centers for Disease Control in the U.S.A.lists causes of death for individual states in 2002.The mortality data for the five leading causes of death for one state is given. $$\begin{array}{lc}\text{ Cause of Death }& \text{ Percent }\\ \text{ Heart Disease }& 28.5\%\\ \text{ Cancer }& 23.2\%\\ \text{ Circulatory diseases and stroke }& 7.5\%\\ \text{ Respiratory diseases }& 5.5\%\\ \text{ Accidents }& 4.8\%\end{array}$$ Which of the following displays is/are appropriate to describe the data for all causes of death? (More than one display may be appropriate.)
I
II
III

A) I,II
B) I,II,III
C) II,III
D) II
E) None of these displays are appropriate.

Both II and III are appropriate displays for describing mortality data for all causes of death. II is a horizontal bar chart, which is effective in comparing the number of deaths for each cause. III is a stacked bar chart, which can show the total number of deaths for each sex and age group, as well as the contribution of each cause to the total number of deaths. I is not appropriate as a display for the data for all causes of death because it only shows the leading causes of death, which may not include less common but still significant causes. Therefore, the correct answer is C - II and III.
