4. In a completely randomized experimental design, 7 experimental units were used for the first treatment, 9 experimental units for the second treatment, and 14 experimental units for the third treatment. F value for testing any significant differences among the means is 4.5 and MSE=4. The corresponding sum of squares due to treatments (SSTR) is      8.     (5%), the degree of freedom associated with error is       9.      (5%), and the total sum of squares (SST) is       10.      (5%)
