Create a scatterplot to see the relationship between the variables Sanitation and Life Expectancy. What is the independent variable? Dependent variable? Find the correlation coefficient, r and describe the relationship between Sanitation and Life Expectancy. Find the equation of the linear regression line. Write the equation below and draw it on the scatter plot. Interpret the slope of the equation. What does it tell you about the relationship between Sanitation and Life Expectancy? Be specific. Interpret the y-intercept of the equation. What does it tell you? Be specific. What percent of the variation in the dependent variable can be explained by this linear relationship? What is this number called? If the 90% of the people in a country have access to Sanitation, what would you predict the Life Expectancy of that country to be? If the Life Expectancy of a country is 73 years, what would you expect the Sanitation rate of that country to be?
