In a completely randomized design 12 experimental units were

In a completely randomized design, 12 experimental units were for the first treatment 15 for the second treatment and 20 for the third treatment. Complete the following analysis of variance

Solution

P-value < 0.001.

SinceP-value is less than 0.05 we reject H0 and conclude that the mean treatment effects are not equal
