1.  CV = 10.0%, and df for EMS = 42.
2.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore an LSD value was
     not calculated.
3.  CV = 9.9%, and df for EMS = 12.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0.10).
