Example 20.4 in the text asks "Do Chimpanzees Collaborate?" The conclusion states: "The data give very strong evidence (p < .0005) that chimpanzees recruit a collaborator more often when faced with a problem that requires a collaborator to solve. That is, chimpanzees recognize when collaboration is necessary, a skill that they share with humans." Assume you saw this conclusion in a research article and wondered if the author's "strong evidence" is the small p-value in parentheses (p < .0005).

Run a paired samples t-test with the CHIMPS.sav data set.

What results justify the "strong evidence" conclusion that chimpanzees collaborate when required?
