The General Social Survey (GSS) is a sociological survey used to collect data on demographic characteristics and attitudes of residents of the United States. In 2010, the survey collected responses from 1,154 US residents. The survey is conducted face-to-face with an in-person interview of a randomly-selected sample of adults. One of the questions on the survey is After an average work day, about how many hours do you have to relax or pursue activities that you enjoy? A 95% confidence interval from the 2010 GSS survey is 3.53 to 3.83 hours.

e) H0: μ = 4; Ha: μ < 4
