a)applying one way ANOVA on above data:
| Source | SS | df | MS | F | P value |
| Between | 1448.0 | 2 | 724.0 | 7.24 | 0.013 |
| Within | 900.0 | 9 | 100.0 | ||
| Total | 2348.0 | 11 |
p value : between 0.01 and 0.025
b)
| critical value of t with 0.05 level and N-k=9 degree of freedom= | tN-k= | 2.262 | |||
| Fisher's (LSD) for group i and j =(tN-k)*(sp*√(1/ni+1/nj) = | 15.99 | ||||
