Question
Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. Penetrability is a measure of the resistance plant roots
meet when they grow through the soil. Low penetrability indicates high resistance. Soil samples were taken from areas that were categorized as Compressed,
Intermediate, and Loose. The analysis below summarizes the data. Is there evidence to support the claim that the mean compression levels differ significantly?
Use a significance level of 0.05.
