Answer:
The taller the baby, the lighter the baby
Explanation:
A correlation coefficient is a number between -1 and 1. The correlation is strong when it is a number closer to -1 or closer to 1 and the relation is independent when it is a number closer to 0.
In this case, we get that the correlation coefficient is -0.12, so there is a weak negative correlation. The negative means that when one variable increases, the other decrease, so the taller the baby, the lighter the baby.
Then, the answer is:
The taller the baby, the lighter the baby
 
        
             
        
        
        
Your answer is 18 :)
work:
pi(2)d
pi(72)
72/2=36=d
2r=d
36/2=18=r
