@Michele_Laino  this one is confusing me?

michele_laino · Answer

I think that the answer can be $affirmative$, since the coefficient of correlation is a measure of how is right the hypothesis of linear relation between the involved variables

michele_laino · Answer

please keep in mind that "correlation coefficient" stands for "coefficient of linear correlation"
