The correct statement is: "There is a strong positive linear association between weight loss and exercise, but the researchers have not proven causation."

Here's why:

1. Correlation does not imply causation. Just because two variables are correlated, it doesn't mean that one causes the other. In this case, while there is a high correlation between exercise and weight loss, it doesn't necessarily mean that exercise causes weight loss. There could be other factors at play.

2. The statement "The researchers proved that exercise causes weight loss, but only for high school students" is incorrect because, as mentioned above, correlation does not imply causation. The researchers have not proven that exercise causes weight loss, only that there is a correlation.

3. The statement "93% of the high school students studied lost weight" is incorrect because the correlation coefficient of 0.93 does not represent a percentage of students who lost weight. It represents the strength and direction of the linear relationship between exercise and weight loss.

4. The statement "The researchers proved that exercise causes weight loss" is incorrect for the same reasons mentioned above. The researchers have not proven causation, only correlation.
