An article in Tropical Science [€œProximate Composition of the Seeds of Acacia Nilotica var Adansonti (Bagaruwa) and Extraction of Its Protein€ (1992, Vol. 32(3), pp. 263€“268)] reported on research extracting and concentrating the proteins of the bagaruwa seeds in livestock feeding in Nigeria to eliminate the toxic substances from the seeds. The following are the effects of extraction time and flour to solvent ratio on protein extractability of the bagaruwa seeds in distilled water:

All values are means of three determinations.

(a) Test the appropriate hypotheses and draw conclusions using the analysis of variance with α = 0.5.

(b) Graphically analyze the interaction.

(c) Analyze the residuals from this experiment.
