A set of n = 15 pairs of X and Y scores has SS_X = 10,SS_Y = 40,and SP = 30.What is the slope for the regression equation for predicting Y from X? A)10/30 B)10/40 C)40/10 D)30/10

Question

Quizplus · Accepted Answer

The slope for the regression equation for predicting Y from X is calculated using the formula slope = SP / SS_X. Given SP = 30 and SS_X = 10, the slope = 30 / 10 = 3, which corresponds to choice D.
