Refer to Exercise A17.9. Weight is a major factor that determines whether a person will need a hip or knee replacement and at what age. To learn more about the topic, a medical researcher randomly sampled individuals who had hip replacement (code = 1) and knee replacement (code = 2) and one of the following categories:
2. Normal range
3. Overweight but not obese
Do the data allow the researcher to conclude that weight and the joint needing replacement are related?
