1. Given the following information, perform the Durbin-Watson test to determine whether firstorder autocorrelation exists: n = 25, k = 5, α = .10, d = .90

2. Test the following hypotheses with α = .05. H0: There is no first-order autocorrelation. H1: There is positive first-order autocorrelation. n = 50, k = 2, d = 1.38
