Amy designed an experiment to test how exercise affects adult men. The resting heart and respiratory rates were measured in fifty men between the ages of 25-55. Once a baseline was established, the men were asked to run on the treadmill for five minutes. The breathing rate and heart rate were recorded every thirty seconds. A graph of her results is below. What can be inferred from the results of Amy's experiment?

• There is no apparent relationship between heart rate and respiratory rate.

• An increase in heart rate correlates with a decrease in respiratory rate.

• There is a positive correlation between heart rate and respiratory rate

• There is no apparent relationship between exercise and heart rate.
