Question

Research shows that even for married couples in two-income households, women perform significantly more housework than men (see Hersh and Stratton 2000). You wish to replicate this study in 2019 and you sample populations of married men and women, all of whom work fulltime outside the home. Housework (Y) is measured in hours and the standard deviations are significantly different from one another. Do your data below support the previous research findings (that women perform more housework)

Women	Men
1 = 29.15	2 = 23.24
S1  = 4.12	S2 = 11.05
N1 = 57	N2 = 57

For each of the following problems:

1. state the research and null hypotheses    
2. compute either the z- or t-statistic
3. decide whether to use a one-tailed or two-tailed test
4. determine the p-value for the hypothesis test
5. decide whether there is evidence to reject the null hypothesis (use a=0.05)
