Question

The “second shift” refers to the housework performed by employed women and employed men when at home. Bianchi et al. (2012) suspected that U.S. employed women perform more “second shift” hours than do U.S. employed men. Using the National Survey of Families and Households (NSFH) data, they reported that in 2010 employed and married American women in the sample performed, on a weekly average, 17.8 hours of total housework (i.e., childcare and house cleaning) while employed and married American men in the sample performed, on average, 10.3 hours of total housework. There were 9,807 women in the sample with a standard deviation of 12.3 hours and 7,795 men in the sample with a standard deviation of 15.7 hours. Test the Null Hypothesis of no difference in the average hours of “second shift” work performed by U.S. women and men.
