For each case, indicate the decision regarding the test of the null hypothesis of no first-order autocorrelation against the alternative hypothesis of positive first-order autocorrelation.

a. k = 2, n = 20, α = .05, d = 1.1

b. k = 2, n = 20, α = .01, d = 1.1

c. k = 5, n = 65, α = .05, d = .95

d. k = 1, n = 31, α = .01, d = 1.35
