Question:

For each of the following tests, determine which of the two sums of absolute ranks (negative or positive) you would choose, the appropriate test statistic, and the rejection region for the Wilcoxon matched-pairs signed rank test:
a. HA: 1 < 2, α = 0.025, n1 = 15
b. HA: 1 > 2, α = 0.01, n1 = 12
c. HA: 1 ≠ 2, α = 0.05, n1 = 9
d. HA: 1 < 2, α = 0.05, n1 = 26
e. HA: 1 ≠ 2, α = 0.10, n1 = 44
