Learning the Basics Question 1. The residuals for 15 consecutive time periods are as follows: Time Period Residual TimsI Period Residual 2 15: 1'3 -3 3 -1 11 +1 4 -5 12 +3 5 +2 13 G 6 +5 14 -4 ? -2 15 -? B +? a}. Plot 1e residuals over time. What conclusion can you reach about line pattern of the residuals over time? h]. Compute the Durhin-Waison statistic. At the 0.05 level of signicance, is there evidence of positive autocorrelation among the residuals? c}- Based on {a} and {b}. what conclusion can you reach about The autocorrelation of the residuals
