Living at home According to the U.S. American Community Survey (ACS), by 2014, for the first time in the history of the ACS, more U.S. 18- to 34-year-olds reported living with a parent than were living independently in their own homes. The survey found that 32.1% were living with parents vs. 31.6% heading a household with a spouse or partner. About 14% were living alone, were a single parent, or lived with roommates. The results are based on a survey of 648,118 respondents (www.pewsocialtrends.org/2016/05/24/for-first-time-in-modern-era-living-with-parents-edges-out-other-living-arrangements-for-18-to-34-year-olds/).

1. Create a 95% confidence interval for the proportion of 18- to 34-year-olds who were living with their parents.

3. Explain in this context what “95% confidence” means.
