This is related to a IR question.

The graphic below is a percentile distribution of weight, being the height the independent variable.
According to the GMAT, we cannot estimate the percentile distribution of height based on the weight.
Common sense, tell me that they are right. But, please could someone provide me a detailed explanation?

Also, is there a source on line in which I could read more theory about this type of graphics evaluated by the GMAT?

Thanks!
