The coefficient of variation for the male pulse rates is __ % The coefficient of variation for the female pulse rates is __%

n 19 As a general rule it can be stated that:     A.       Association and causation are two terms that mean the same thing as regression-correlation analysis.     B.       Correlation shows association but does not prove causation.           C.       Regression analysis shows causation and correlation analysis proves causation.       D.     All of the above are correct.
