When the correlation coefficient is intermediate, it implies that there is some degree of association between X and Y, but the relationship is not perfect. This means that there will be some variation in the Y scores associated with a single X score, and prediction of Y from a known X score will have some error. However, this does not necessarily mean that all data points fall on the regression line. In fact, if there is some degree of scatter in the data, then the data points may not all fall on the regression line. Therefore, D is not true for an intermediate correlation coefficient.
