1.  CV = 7.3% and df for EMS = 36.
2.  CV = 7.1% and df for EMS = 36.
3.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD value was
     not calculated.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected
LSD (P = 0/10).
