Abiology student is studying digestive systems, and the particular chemicals released by organisms to break food down into a digestible form. it appears that the chemical released to break down carbohydrates (c) is different to the chemical released to break down proteins (p). the student is interested in the effect of chemicals p and c on digestion, and the interaction of these two chemicals. the student's biology class performs a test where four samples of organic material are treated with the two chemicals. one sample receives neither chemical, one sample receives c only, one sample receives p only, and one sample receives both c and p. the amount of decomposition in the organic material is recorded. a two-way anova test is conducted by the student, to determine the significance of the effect of each chemical, and the interaction of the two chemicals. a level of significance of 0.05 is used. an output table for this test and a means plot for the samples collected are included below: source f puvalue chemical c chemical p interaction error total sum of squares df mean squares 219.2103 219.2103 208.0844 208.0844 151.5528 151.5528 4,690.92 156 30.07 5,269.7675 159 7.29 6.92 5.04 0.0077 0.0094 0.0262 a) based on the output table for the anova test: it can be concluded that there is no interaction between chemical and chemical p in relation to their effect on food decomposition it can be concluded that there is interaction between chemical c and chemical p in relation to their effect on food decomposition there is not enough evidence to make a conclusion about the interaction of chemical and chemical p in relation to their effect on food decomposition b) four friends of the biology student look at the means plot and each friend makes a comment about it: arnold: '
