Aresearcher states that bone density in women is negatively associated with age. this means: a. above average values of age tend to accompany below average values of bone density.
b. above average values of age tend to accompany above average values of bone density.
c. below average values of age tend to accompany below average values of bone density.
d. older women aren't any more likely than younger women to have below average bone density.

This means that the older the woman, the lower the bone density. So older women are more likely to have below average bone density: the correct answer is

A. above average values of age tend to accompany below average values of bone density.

A. above average values of age tend to accompany below average values of bone density.  

If we evaluate the relationship between bone density and age of women, it is described as having a negative relationship or correlation. In simpler terms, in the context of development if one variable increases then the other in response, decreases. Paradoxical. Thus, like in this situation, as women gets older the lesser probability and susceptibility they are to have bone density complications.
