  b. the Wilcoxon signed-ranks test.
  c. Friedman's test.
  d. the Kruskal-Wallis test.

Question 2

Assume that we asked 20 subjects to participate in a smoking cessation study. We recorded their craving for a cigarette before and after applying a nicotine patch. One reason we might want to use a distribution-free test is because

  b. there are some outliers that we don't want to have undue influence on the results.
  c. the data are normally distributed.
  d. the subjects are all male.

Question 3

When we have relatively large sample sizes, the distribution-free tests for comparing two groups or sets of data discussed in the text have
 
  a. a chi-square approximation.
  b. a normal approximation.
  c. no solution.
  d. problems.

Question 4

With at least some distribution-free tests, a two-tailed test
