If a sample of 25 pairs of data yields a correlation coefficient, r, of 0.390 and the scatterplot displays a linear trend, can you use the regression equation to make predictions, assuming your x-values are within the domain of the data set? Choose your answer from the multiple choice answers below  A.) Yes, because rcrit =  0.396 and the regression coefficient, r, is less than this value. B.) Yes, because rcrit = 0.381 and the regression coefficient, r, is greater than this value. C.) No, because rcrit =  0.381 and the regression coefficient, r, is greater than this value. D.) No, because rcrit =  0.396 and the regression coefficient, r, is less than this value.

Choose your answer from the multiple choice answers below 

A.) Yes, because rcrit =  0.396 and the regression coefficient, r, is less than this value.

B.) Yes, because rcrit = 0.381 and the regression coefficient, r, is greater than this value.

C.) No, because rcrit =  0.381 and the regression coefficient, r, is greater than this value.

D.) No, because rcrit =  0.396 and the regression coefficient, r, is less than this value.
