ER Visits for Injuries The graph shows the rates of visits to the ER for injuries by gender and by age. Note that we are concerned with the rate per 100 people of that age and gender in the population. (Source: National Safety Council 2004)
a. Why does the National Safety Council give us rates instead of numbers of visits?
b. For which ages are the males more likely than the females to have an ER visit for an injury? For which ages are the men and women similar? For which ages do the women have more visits?
