Traditionally, the work week for a U.S. adult who is considered "full-time" is 40 hours a week. According to the 2012 General Social Survey, a sample of 583 female adults responded the number of hours worked the previous week averaged 37.0 and with a standard deviation of 15.1 hours.

Is there sufficient evidence to conclude that female workers in our country work generally less than 40 hours per week?
