Question

Research has shown that people are more likely to show dishonest and self- interested behaviors in darkness than in a well-lit environment (Zhong, Bohns, & Gino, 2010). In one experiment, participants were given a set of 20 puzzles and were paid $0.50 for each one solved in a 5-minute period. However, the participants reported their one performance and there was no obvious method for checking their honesty. Thus, the task provided a clear opportunity to cheat and receive understand money. One group of participants were tested in a room with dimmed lighting and a second group was tested in a well-lit room. The reporter number of solved puzzles was recorded for each individual. The following data represent results similar to those obtained in the study.

Well Lit Room	Dimly Lit Room
7	9
8	11
10	13
6	10
8	11
5	9
7	15
12	14
5	10

a)Is there a significant difference in reported performance between the two conditions? Use a two- tailed test with = .01.

b)Compute the value of r² (percentage of variance accounted for) these data.
