Question:

Do nice guys really finish last? Refer to the Nature (Mar.

20, 2008) study of whether “nice guys finish last,” Exercise 11.22 (p. 625). Recall that Boston-area college students repeatedly played a version of the game “prisoner’s dilemma,”

where competitors choose cooperation, defection, or costly punishment. At the conclusion of the games, the researchers recorded the average payoff and the number of times LO9 

punishment was used for each player. Based on a scatterplot of the data, the simple linear regression relating average payoff (y) to punishment use (x) resulted in SSE = 1.04.

a. Assuming a sample size of n = 28, compute the estimated standard deviation of the error distribution, s.

b. Give a practical interpretation of s.
