Depression engulfs millions of Americans every day. A federal study reported that 10.9% of adults aged 18–24 identified with some level of depression versus 6.8% of adults aged 65 or older (The Boston Globe, October 18, 2010). Suppose 1,000 young adults (18–24 years old) and 1,000 older adults (65 years old and older) responded to the study. Let young adults and older adults represent population 1 and population 2, respectively. (You may find it useful to reference the appropriate table: z table or t table)
