Solved: In business, do nice guys finish first or last?
Chapter 11, Problem 66E(choose chapter or problem)
In business, do nice guys finish first or last? Refer to the Nature (March 20, 2008) study of the use of punishment in cooperation games, Exercise 11.14 (p. 614). Recall that college students repeatedly played a version of the game “prisoner’s dilemma,” and the researchers recorded the average payoff and the number of times cooperation, defection, and punishment were used for each player.
a. A test of no correlation between cooperation use (x) and average payoff (y) yielded a p-value of .33. Interpret this result.
b. A test of no correlation between defection use (x) and average payoff (y) yielded a p-value of .66. Interpret this result.
c. A test of no correlation between punishment use (x) and average payoff (y) yielded a p-value of .001. Interpret this result.

ANSWER:
Step 1 of 3
a) A test of no correlation between cooperation use (x) and average payoff (y)
yielded a p-value of 0.33. That is a test of the null hypothesis is 
p-value of 0.33. According the p-value approach, if the p-value is less than
(0.01 or 0.05) otherwise not. We do not reject the null hypothesis,
the
