The following table shows the percentage household savings rates in Canada and in the U.S. from 2003 to 2017. Use these data to develop a linear regression model to forecast the percentage change in the Canadian savings rate by the percentage change in the U.S. savings rate. Compute a Durbin-Watson statistic to determine whether significant autocorrelation is present in the model. Let α = 0.05.
