Testing group differences
Let's test the hypothesis that Alzheimer's Disease is characterized by reduced brain volume.
We can perform a two-sample t-test between the brain volumes of elderly adults with and without Alzheimer's Disease. In this case, the two population samples are independent from each other because they are all separate subjects.
For this exercise, use the OASIS dataset (df) and ttest_ind to evaluate the hypothesis.
