Anova was used because four groups were compared (more than two)

Experiment 2
Rat T - Test = 0.867403497
not significant
T-Test was used because only two groups were being compared



Analysis

Experiment 1

Based on the fact that the Anova test resulted in a p-value less than .05 (actual value=.00035), we determined that there was a statistical significance of the data in the human groups. Using the Bonferoni test and the corrected p-values compared to the T-test, we found that our data was less than .0083, meaning they were all significant.

Experiment 2

Based on our T-test value of .87, we found that there was no significance because the data was greater than .05.



Summary/Discussion

Based on the ANOVA test for the human subjects it was determined that the data was statistically significant, while the high p-value determined by the t-test for the rat subjects showed that the statistical information for this set of subjects was insignificant. After performing a Bonferroni correction for all the human sample groups, it was determined that all the differences in dosages of the drug were statistically significant. Based on this information, it can be concluded that taking five to fifteen milligrams of the drug affects the Inflammotin levels in the elderly human population.
