For the following question please provide:

i) your null hypothesis, alternative hypothesis, and significance level

ii) the statistical test you used to address the study hypothesis and a description of why

you chose the test

iii) your conclusions in the context of the study and evidence that supports your

conclusions including test statistics, p-values, and effect size

A study evaluated the immune response to stress. Researchers quantified leucocyte concentrations in the blood of mice exposed to different levels of stress defined as levels of "repeated social defeat". Social defeat consisted of confronting the test mice with a trained, highly aggressive intruder mouse. The four experimental treatments included: i) 2 days of repeated social defeat, ii) 4 days of repeated social defeat, iii) 6 days of repeated social defeat, and iv) a control in which mice were not subjected to social defeat. Using the data provided, test the hypothesis that the repeated social defeat at different durations had an effect on leucocyte concentrations, and if applicable, identify any differences between treatments.
