Given that if the coefficient of determination is a positive value, then the regression equation _________
While r the correlation coefficient represents thelinear association between two variables, r has an attached sign.
A positive r represents positive slope and negative r negative slope
But coefficient of determination is the square of r and hence from this R^2 value alone we cannot conclude whether positive or negative relation exists.
As a result,
c. could have either a positive or a negative slope
