Soil quality: Soil scientists conducted an experiment in which the mineral gypsum was added in four different amounts to soil specimens to try to control the acid level of the soil. Three soil specimens received each amount added. The response variable is pH. which is a measurement of the acid level. The results are as follows. Construct an ANOVA table.
