Specify the test statistic and the rejection region for the Wilcoxon signed rank test for the paired difference design in each of the following situations:
a. H0: Two probability distributions, A and B, are identical
Ha: The probability distribution for population A is shifted to the right or left of the probability distribution for population B
n = 20, α = .10
b. H0: Two probability distributions, A and B, are identical
Ha: The probability distribution for population A is shifted to the right of the probability distribution for population B
n = 39, α = .05
c. H0: Two probability distributions, A and B, are identical
Ha: The probability distribution for population A is shifted to the left of the probability distribution for population B
n = 7, α = .005
