McConaughy (1980) has argued that younger children organize stories in terms of simple descriptive (“and then. . .”) models, whereas older children incorporate causal statements and social inferences. Suppose that we asked two groups of children differing in age to summarize a story they just read. We then counted the number of statements in the summary that can be classed as inferences. The data follow:

Younger Children: 0103252

 Older Children: 476487

a. Analyze these data using the two-tailed rank-sum test.

b. What can you conclude?

c. How would you go about analyzing these data if you had access to a program that would do resampling for you?
