A Research Group Is Studying the Correlation Between BMI and Blood

A research group is studying the correlation between BMI and blood pressure in a random sample of children age 12-16.  After collecting data, they conduct a correlation analysis at a 1% significance level.  The researchers find that BMI correlates with systolic blood pressure with a coefficient of r = 0.46 (p <0.001) and diastolic blood pressure with a coefficient of r = 0.37 (p <0.001) .  Which of the following is the most accurate interpretation of these results?

A) An increase in BMI causes a statistically significant increase in blood pressure in children
B) Childhood obesity significantly increases the risk of cardiovascular disease later in life
C) There is a statistically significant negative linear relationship between BMI and blood pressure in children
D) There is a statistically significant positive linear relationship between BMI and blood pressure in children
E) There is no statistically significant linear relationship between BMI and blood pressure in children
