Does the list of their means seem to indicate any "outliers"? ___________

F=________      Critical value: α=0.05:________   Reject H0?:____

p_value=_______   Reject H0?:____

If you are rejecting H0, 
  what does the Scheffe test show as problem pairs: rows________  
  what does the Tukey test show as problem pairs:   rows________
