We had a look at two broad groups in our study – humans and rats. These groups were then separated into subgroups according to treatment. Analysis of results is as follows: Data Inflammotin (pg/ml) Human 0mg 5mg 10mg 15mg 5.23 10.72 100.19 793.17 1.01 9.29 75.92 476.67 4.23 8.46 23.46 771.45 1.87 10.19 70.87 795.09 3.67 7.29 19.27 181.27 2.98 7.54 99.65 752.78 5.83 8.67 38.37 934.23 5.24 6.15 76.26 554.87 4.27 10.92 35.25 692.23 4.01 10.09 76.98 627.65 AVERAGE 3.834 8.932 61.622 657.941 Std.

P-score analysis of every possible combination of these groups showed a statistically significant difference (p < 0.008333333) for each and every one of these pairings as well as the ANOVA. Based on these numbers we can predict that treatment will have an effect on blood inflammotin levels and that the higher the dosage (up to 15mg), the greater the response. Experiment 2 Rat trials were slightly less complicated as we only compared treatments of 0mg and 10mg of LPS. The p-value between these two groups is 0.867 – this is not statistically significant and so the treatment is deemed to have no effect.
