Rat Study
A T-Test was performed because there are only two different dosages: 0mg and 10mg. The p-value for this study is not significant because it is greater than 0.05.

Human Study
ANOVA was performed because there were four different dosages: 0mg, 5mg, 10mg, and 15mg. Since the p-value of the ANOVA was less than 0.05, it was significant. Therefore, a Bonferroni Correction had to be performed to see if the results were significant.


In the rat study, the difference in inflammotin levels caused by the LPS was not significant because the p-value was greater than 0.05. In contrast, the difference in inflammotin levels caused by the LPS in the human study was significant because the p-value was less than 0.05. The significance between each change in dose was also significant because the p-value was less than 0.00833. 0.00833 was used because it is 0.05/6, 6 being the number of T-Tests that were run. This means that the LPS works to increase inflammotin levels in humans but does not necessarily work to increase inflammotin levels in rats. This could be a result of how few rats were tested compared to humans. At each dosage, ten humans were tested but only five rats were tested. Biological differences could also be a factor.
