Question

Exercises pertain to critical values for a Wilcoxon signed-rank test. Use Table V in Appendix A to determine the critical value(s) in each case. For a left-tailed or two-tailed test, you will also need the relation W1-A = n(n + 1)/2 - WA.

Sample size = 19; Signicfiance level = 0.10

a. Right tailed
b. Left tailed
c. Two tailed
