1. What is the dependent variable and independent variable for this analysis? Why?
2. Use an appropriate plot to investigate the relationship between the two variables. On the same plot, fit a linear trend line.
3. Estimate a simple linear regression model and present the estimated linear equation. Diplay the regression summary table and interpret the intercept and slope coefficient estimates of the estimated linear model.
4. Interpret the value of the coefficient of determination, R-squared (R2).
