A group essay has reported that there is a correlation of r= -0.59 between the eye colour (brown, green,blue) of a board members of bank and the amount of risk that is crucial to the regulator. This indicates:

1. the students need to do further study to explain the causes of this negative correlation.
2. financial risk is less harmful to one eye colour than the others.
3. the risk level of bank goes down as the eye colour of the executives changes.
4. the students need to take a course in research methods further because correlation is not an appropriate measure of association in this situation.
5. one must always consider the eye colour of executives in making statements about the effect of risk.
