If SS_XY = -16.32 and SS_X = 40.00 for a set of data points,then what is the value of the slope for the best-fitting linear equation? A) -0.41 B) -2.45 C) positive D) there is not enough information; you would also need to know the value of SS_Y

Question

Quizplus · Accepted Answer

The slope (b) of the best-fitting linear equation is calculated using the formula b = SS_XY / SS_X. Substituting the given values, b = -16.32 / 40.00 = -0.408, which rounds to -0.41.
