The World Health Organization maintains a wide range of data collections related to global health and well-being. The file InfantMortality.xlsx contains information for a random sample of countries (n: 32) on various health issues. A researcher is investigating the relationship between Total Expenditure on Health as % of GDP 2003 (TExpen_2003) and Infant Mortality rate (per 1000 live births) in 2004 (IM_2004). Specifically, she wants to answer the following research question: Research Question: "Is there a linear relationship between Total Expenditure on Health as % of GDP 2003 (TExpen_2003) and Infant Mortality rate (per 1000 live births) in 2004 (IM_2004)?" To help you check the relevant assumptions of the simple linear regression, four graphs are provided below: Figure 1 8 Figure 2 N o 8 E 3 g E' U) (D E \":2 E E \"3 \" 3 3 t 3 ' u: o I 3 \"'3 i: O u) E :2 g a E; '13 E 8 5 s t N 8 Lu .5 g E 2 4 6 8 10 l- 50 60 70 80 90 100 110 120 Total Expenditure on Health as % ofGDP 2003 Infant Mortality rate (per 1000 live births) in 2004 Figure 3 Figure 4 to m
