Question

2.2.3 The OLS line $\hat{y} = \hat{\beta}_0 + \hat{\beta}_1 x$ is shown on the figure as a dashed line, and evidently $\hat{\beta}_1 < 1$. Does this suggest that prices are lower in 2009 than in 2003? Explain your answer. 2.2.4 Give two reasons why fitting simple linear regression to the figure in this problem is not likely to be appropriate.
