18. Regarding the standard error of the estimate (SEE or Sy/x)-more than one answer may be correct a. The SEE describes the dispersion of x, y points around the regression line b. If the random errors for both methods are identical, the SEE will be approximately 1.4 times a typical SD c. The SEE is used to evaluate the accuracy of a method based on hemolysis and lipemia interference experiments The SEE is sensitive to random error d.
