True or False
_____I. If anegative correlation exists between X and Y, and a new data pointis added whose Z_X = -2.5 andZ_Y = 2.5, |r| will decrease.
_____J. If apositive correlation exists between X and Y, and a new data pointis added whose Z_X = 2.5 andZ_Y = 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.

I If a negative correlation exists between X and Y and a new data point is added whose ZX 25 and ZY 25 r will decrease Since ZX 25 and ZY 25 are of opposite signs and absolute value is greater than 2 the absolute value of negative correlation will increase The statement is False J If a positive correlation exists See Answer
