True or False
_____I. If anegative correlation exists between X and Y, and a new data pointis added whose ZX = -2.5 andZY = 2.5, |r| will decrease.
_____J. If apositive correlation exists between X and Y, and a new data pointis added whose ZX = 2.5 andZY = 2.5, |r| will decrease.
_____K. In simplelinear regression predicting Y from X, the unstandardizedcoefficient of the X variable will always equal the Pearsonr between X and Y. (Assume X and Y are not measured asz scores.)
_____L. In simplelinear regression predicting Y from X, the standardized coefficientof the X variable will always equal the Pearson r betweenX and Y.
_____M. In multipleregression predicting Y from two X variables, the standardizedcoefficient for the first X variable will always equal the Pearsonr between that X and Y.
