A scatter plot displays the relationship between 'daily hours spent exercising' and 'resting heart rate' for a group of adults. The plot shows a general downward trend, but with significant spread around the trend line, and a few outliers with very high heart rates despite high exercise hours. Which conclusion is best supported by this data?
✓ Correct Answer: Option B
A downward trend indicates a negative correlation. 'Significant spread' and 'outliers' suggest other variables are at play, meaning exercise isn't the sole determinant and a perfect prediction isn't possible. Causation cannot be definitively established from correlation alone.
