1.  CV = 16.2% and df for EMS = 69.
2.  The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, a LSD
     value was not calculated.
3.  CV = 10.8% and df for EMS = 42.
Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD (P = 0/10).
