Answer to Question 1

Based on the data provided:
dL = 0.97 and dU = 1.41
The decision is made as follows:
If d < dL = 0.97 or d > 4 - dL = 3.03, reject H0 and conclude that the autocorrelation is present.
If 0.97 = dL  d  dU =1.41, or 2.59 = 4 - dU  d  4 - dL = 3.03, we say that the test is inconclusive.
If 1.41 = dU  d  4 - dU = 2.59, conclude that there is no evidence of autocorrelation
Since d = 1, we conclude that there is no evidence of autocorrelation.

Answer to Question 2

TRUE
