2.35 Does Stress Affect Academic Performance? Students in the ACHA-NCHA survey were asked, "Within the last 12 months, has stress negatively affected your academics?" Figure 2.4(a) shows a segmented bar chart for response frequencies, while Figure 2.4(b) shows a segmented bar chart for response relative frequencies as percents. Possible responses were "I haven't had any stress," shown in red, "I've had stress but it hasn't hurt my grades," shown in green, or "I've had stress and it has hurt my grades," shown in blue. (a) Did more males or more females answer the survey or did approximately equal numbers of males and females participate? Is graph (a) or (b) more helpful to answer this question? (b) Did a greater number of males or females say they had no stress or is it approximately equal between males and females? Is graph (a) or (b) more helpful to answer this question?
