Xr03-77 During 2002 in the state of Florida, a total of 365,474 drivers were involved in car accidents. The accompanying table breaks down this number by the age group of the driver and whether the driver was injured or killed. (There were actually 371,877 accidents, but the driver’s age was not recorded in 6,413 of these.)

a. Calculate the injury rate (per 100 accidents) and the death rate (per accident) for each age group.

b. Graphically depict the relationship between the ages of drivers, their injury rate (per 100 accidents), and their death rate.

c. Briefly describe what you have learned from these graphs.

d. What is the difference between the information extracted from Exercise 3.9 and this one?
