Question
Resistance training is a popular form of conditioning aimed at enhancing sports performance and is widely used among high
school, college, and professional athletes, although its use for younger athletes is controversial. A random sample of 4111
patients between the ages of 8 and 30 admitted to U.S. emergency rooms with the injury code "weightlifting" was obtained.
These injuries were classified as "accidental" if caused by dropped weight or improper equipment use. The patients were also
classified into the four age categories 8–13 years, 14–18, 19–22, and 23–30.
A two-way table of the results is given.

Compare the distributions of ages for accidental and nonaccidental injuries. Use percents and create a bar graph using your
preferred software to help you answer the question.
Select the image of the bar graph representing the percents for the distribution of ages for accidental and not accidental
injuries. (The four bars in each of the Accidental and Not Accidental categories are displayed in increasing age group order:
the first bar for 8 -13, then 14 - 18, then 19 - 22, and then the rightmost bar is for 23 - 30.)

that are not accidental, the percentage of relatively older lifters is larger.
Among accidental weight-lifting injuries, the percentage of relatively younger lifters is smaller, while among the injuries
that are not accidental, the percentage of relatively older lifters is smaller.
Among accidental weight-lifting injuries, the percentage of relatively younger lifters is approximately the same as it is
for relatively older lifters, while among the injuries that are not accidental, the percentage of relatively older lifters is
smaller.
