Answer to Question 1

T

Answer to Question 2

dL = 1.29 and dU = 1.78
The decision is made as follows:
If d < dL = 1.29, reject H0 and conclude that positive autocorrelation is present.
If 1.29 = dL  d  dU = 1.78, we say that the test is inconclusive.
If d  dU = 1.78, we conclude that there is no evidence of positive autocorrelation.
Since d = 1.12, we reject H0 and conclude that positive autocorrelation is present.
