Study Questions

The following set of questions utilizes data from the Population Reference Bureau (PRB) on the relationship between women's literacy (ages 15-24) and the prevalence of HIV in sub-Saharan Africa. Using the PRB's Data Finder tool, data were assembled for 14 countries in sub-Saharan Africa through the year 2011 and are shown below.

Country	Female Literacy Rate	Percent Women With HIV
Angola	65	2.4
Botswana	96	29.2
Democratic Congo	78	4.1
Eritrea	84	0.9
Madagascar	68	0.1
Malawi	85	13.2
Namibia	95	15.7
Nigeria	65	4.4
Rwanda	77	3.5
Sudan	82	1.3
Swaziland	95	30.3
Tanzania	76	6.8
Togo	80	3.8
Zambia	68	16.0

1. A researcher advances the hypothesis that women in countries with lower female literacy rates tend to see a greater percentage of the female population infected with HIV. What is the independent variable here? What is the dependent variable here?
2. Several statistics were calculated from these data for both the independent and the dependent variables. Identify (i.e., name) the statistic summarizing the independent and dependent variables below.
