Plain-text version
Given the linear regression Y=α+β X; a very high correlation between variables X and Y necessarily implies that (A) The slope coefficient β is statistically significant (B) The observations (x,y) lie along a straight line (C) Small changes in X cause large changes in Y (D) The regression line is steep
Also written as: Given the linear regression Y=alpha+beta X; a very high correlation between variables X and Y necessarily implies that
