According to the data, how does a person's relative risk of premature death change in correlation to changes in physical activity?
A. The risk of dying prematurely increases as people become more physically active.
B. The risk of dying prematurely does not change in correlation to changes in physical activity.
C. The risk of dying prematurely declines as people become more physically active.
D. The risk of dying prematurely declines as people become less physically active

As physical activity increases, the relative risk of premature death changes.
At 30 minutes, the relative risk is 1; at 420 minutes, it's 0.615.
The relative risk declines as physical activity increases.
Therefore, the risk of dying prematurely declines as people become more physically active.

Explanation

Analyze the problem and data We are given a table that shows the relationship between minutes per week of physical activity and the relative risk of premature death. We need to analyze the data to determine how the relative risk changes as physical activity increases.

Observe the trend Let's examine the data points:



At 30 minutes of activity, the relative risk is 1.
At 90 minutes of activity, the relative risk is 0.8.
At 180 minutes of activity, the relative risk is 0.73.
At 330 minutes of activity, the relative risk is 0.64.
At 420 minutes of activity, the relative risk is 0.615.

As the minutes of physical activity increase, the relative risk of premature death decreases.

Conclusion Based on the observed trend, the risk of dying prematurely declines as people become more physically active.

Examples
Understanding the correlation between physical activity and relative risk of premature death can help individuals make informed decisions about their lifestyle. For example, if a person increases their physical activity from 30 minutes to 90 minutes per week, their relative risk of premature death decreases from 1 to 0.8. This information can be used to promote the benefits of regular exercise and encourage people to adopt healthier habits.

The risk of dying prematurely declines as people become more physically active. Based on the data observed, increased physical activity correlates with lower relative risk values. Therefore, the correct answer is C: The risk of dying prematurely declines as people become more physically active.
