A) It is not possible to calculate the difference between correlations from different groups.
B) If the difference between correlations is not statistically significant, then there is no difference in the relationship between height and weight for women and men.
C) A difference in the slopes calculated for the correlations indicates an interaction between gender and height in predicting weight.
D) If the correlation is the same in both groups, then the intercepts and slopes for the bivariate regression equation are the same for women and men.
