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. Examples of correctly entered answers:
y^=4.913+17.347x
y^=7.553-11.225x
Linear regression equation calculator:
3. Use the regression equation to find the percent of women receiving prenatal care for a country that spends 5.0% of GDP on health expenditure
Enter amount to nearest thousandth; do not include percent sign
4. Use the regression equation to find the percent of women receiving prenatal care for a country that spends 12.0% of GDP on health expenditure
Enter amount to nearest thousandth; do not include percent sign
