4. For a sample of bivariate data, you calculate the correlation coefficient to be r= -0.4. Using the general rules in the Bivariate Data and Correlation video, this correlation coefficient value suggests that there is: * no linear relationship between the two variables. a weak, positive relationship between the two variables. a weak, negative relationship between the two variables. a moderate, positive relationship between the two variables. a moderate, negative relationship between the two variables. a strong, positive relationship between the two variables. O a strong, negative relationship between the two variables.
