Use the following to answer question:
Figure 7.6 
-(Figure 7.6) Which of the following statements is (are) TRUE?

Quizplus · Accepted Answer

From figure 7.6, we can see that there is a negative correlation between the number of hours of exercise per week and the BMI. As the number of hours of exercise increases, the BMI decreases. Therefore, statement III is true. However, we cannot conclude that regular exercise causes a decrease in BMI because this is an observational study and not a randomized controlled trial. Therefore, statement I is false. Statement II is not supported by the data in the graph, as there are many individuals with a BMI less than or equal to 25 who exercise less than 3 hours per week.
