When the assumption of independent residuals is violated (i.e. when residuals exhibit autocorrelation), the Durbin-Watson statistic is used to test for significant autocorrelation among the residuals. The other answer choices are incorrect because normality of residuals is a different assumption and is tested using other methods such as a normal probability plot, and the presence of significant correlation among variables is tested using correlation coefficients such as Pearson's correlation coefficient.

When the Assumption of __________ Residuals (Error Terms)is Violated,the Durbin-Watson
