Answer #1

applying ANOVA"

Source of Variation SS df MS F P-value
Between Groups 398.750 3 132.917 7.877 0.005
Within Groups 168.750 10 16.875
Total 567.500 13

a)SST =567.50

b)SSB =398.75

SSW =168.75

c)as p value is less than 0.05 , we reject HO and conclude that at least one mean is different from others
