Which statement correctly justifies the type of association between x and y? А. They have a weak negative linear association because the correlation coefficient is negative. They have a strong negative linear association because the correlation coefficient is close to -1. С. They have a strong positive linear association because the correlation coefficient has a large value. D. They have a nonlinear association because the correlation coefficient is negative.
