An article in Tropical Science, "Proximate Composition of the Seeds of Acacia Nilotica var Adansonti (Bagaruwa) and Extraction of Its Protein" (1992, Vol. 32, No. 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: Percentage of Protein Extracted at Time (min) Flour: Solvent Ratio (w/v) (%) 30 60 90 120 3 30.4 46.2 30.9 30.6 36.6 44.4 29.8 21.9 7 32.4 42.1 28.5 23.4 37.2 41.4 27.8 34.3 11 28.6 39.8 29.5 29.2 33.1 43.9 30.7 28.9 All values are means of three determinations. (a) Test the appropriate hypotheses and draw conclusions using the analysis of variance with a = 0.05. The time effect is significant, the solvent ratio effect is significant, the interaction between the time and solvent ratio effects is not significant. (b) Graphically analyze the interaction. The interaction effect in this model is strong (c) Analyze the residuals from this experiment. Yes. Does the normality assumption appear reasonable? >
