Assume you're interested in the mental health effects of the "caregivers" caring for th elderly with Alzheimer's disease. Specifically, you expect that such caregivers will suffer from significantly elevated levels of depression as compared to the general population. To measure depression in care-givers, you use a standard test of depression (STD) on which scores range from zero to 40, with high scores indicating higher levels of clinical depression. The mean in the general (normal) population of on this test is µ = 20. You get permission from ten caregivers who have worked in a ocal assisted living facility for Alzheimer's patients for over two years to participate in wour study. They are administered the STD and their scores are below. 8, 33, 32, 22, 31, 29, 21, 26, 17, 25 16
