Explanation / Answer
From Excel
SST=118
SS with in=21.67
SS Between=96.3
A) F critical value=3.6823
B) Since P=0.00000< 0.05 we conlcude that the group means are significant.
C) Since we reject the H0
ie., Atleast we one group mean is different
Next we need to find which is significantly differ for that we need to apply Tukey Test
