Q2A The World Bank collected data on the percentage of GDP that a country spends on health expenditures ("Health expenditure," 2013) and also the percentage of women receiving prenatal care ("Pregnant woman receiving," 2013). The data for the 15 countries where this information are available for the year 2011 is in the table below: Health Expenditure (% of GDP) Prenatal Care (%) 9.6 47.9 3.7 54.6 5.2 93.7 5.2 84.7 10.0 100.0 4.7 42.5 4.8 96.4 6.0 77.1 5.4 58.3 4.8 95.4 4.1 78.0 6.0 93.3 9.5 93.3 6.8 93.7 6.1 89.8 2. Use technology to determine regression equation between percentage GDP spent on health and percentage of women receiving prenatal care. Enter regression equation the format as follows: y^=a+bx with slope rounded to nearest thousandth and y-intercept value rounded to nearest thousandth.
