**Question #5 For students with last names beginning with Q-T:**
16. In a recent study, Piff, Kraus, Côté, Cheng, and Keltner (2010) found that people from lower socioeconomic classes tend to display greater prosocial behavior than their higher-class counterparts. In one part of the study, participants played a game with an anonymous partner. Part of the game involved sharing points with the partner. The lower economic class participants were significantly more generous with their points compared with the upper-class individuals. Results similar to those found in the study, show that \( n = 12 \) lower-class participants shared an average of \( M = 5.2 \) points with \( SS = 11.91 \), compared to an average of \( M = 4.3 \) with \( SS = 9.21 \) for the \( n = 12 \) upper-class participants.
1. Are the data sufficient to conclude that there is a significant mean difference between the two economic populations? Use a two-tailed test with \( \alpha = .05 \).
2. Construct an 80% confidence interval to estimate the size of the population mean difference.
