Do women tend to spend more time on housework than men? If so, how much more? A study reported the results shown in the table to the right for the number of hours spent on housework per week. Complete parts a through d below. Gender Sample Size Mean Women Men Housework Hours The standard error is se= 0.9366. (Round to four decimal places as needed.) 477 500 a. Based on this study, calculate how many more hours per week, on the average, women spend on housework than men. 31.7 17.3 On average, women spend 14.4 more hours per week on housework. b. Find the standard error for comparing the means. What factor causes the standard error to be small compared to the sample standard deviations for the two groups? Clear all Standard Deviation 15.8 13.3 The large sample sizes small compared to the sample standard deviations for the two groups. cause the standard error to be to c. Calculate the 95% confidence interval comparing the population means for women (w) and men (HM). Interpret the result including the relevance of 0 being within the interval or not. The 95% confidence interval for (Hw-HM) is from Check answer
