Question:

J. Engle et al. explored wheat€™s resistance to a disease that causes leaf-spotting, shriveling, and reduced yield in the article €œReaction of Commercial Soft RedWinter Wheat Cultivars to Stagonospora nodorum in the Greenhouse and Field€ (Plant Disease, An International Journal of Applied Plant Pathology, Vol. 90, No. 5, pp. 576€“582). Fields of soft red winter wheat were subjected to the pathogen Stagonospora nodorum during the summers of 2000€“2002. Afterward, the fields were rated on a scale of 0 (resistant to the disease) to 10 (susceptible to the disease). The following table gives the rankings of the fields tested during the three summers.

At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in mean resistance to Stagonospora nodorum among the three years of wheat harvests? (T1 = 55, T2 = 84.2, T3 = 46, and _x2i = 1,108.48.
