In 1989, fathers who stayed at home were surveyed about why they stayed at home. A similar survey was carried out in 2012. The fathers€™ responses and the relative frequencies are described by the multiple bar graph in Fig. 19 for both years.

a. What percentage of fathers in the 2012 study stayed at home because they were unable to find work?
b. From inspecting the multiple bar graph, a student concludes that 35% of all American fathers who stayed at home in 2012 stayed at home because they were ill or disabled. What would you tell the student?
c. Why did most fathers in the 1989 study stay at home? What percentage of fathers in the 1989 study stayed home for that reason?
d. The number of fathers who stayed at home increased from 1.1 million in 1989 to 2.0 million in 2012. Although the number of all fathers increased from 1989 to 2012, that increase alone cannot account for the large percentage growth in fathers who stayed at home. Assuming the live-at-home fathers surveyed represent all live-at-home fathers really well, what are the other reasons for the increase in stay-at-home fathers?
e. Why is it important that the vertical axis of the multiple bar graph describes relative frequencies and not frequencies?
