# Question

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
