Cellulose activity (units/mg protein) in 4 genetic variants of a fungus species was measured in 5 randomly selected cultures of each variant. Is there a difference in activity of this enzyme in the four variants? Note that the variants are chosen at random; thus we are not interested in specific means, only in knowing if added variation is introduced
