8. The interpersonal Reactivity Index is a survey designed to asses four different types of empathy. One type of empathy, called Empathetic Concern, measures the tendency to feel sympathy and compassion for people who are less fortunate. The index ranges from 0 (less empathetic) to 28 (more empathetic). The following data representing random samples of 16 males and 16 males, are consistent with results reported in psychological studies. Boxplots show that is reasonable to assume that the populations are approximately...
