Researchers are interested in the relationship between socio-economic class and unethical behavior in US adults. Therefore, 129 University of California undergraduates at Berkeley were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that they were for children in a nearby laboratory, but that they could take some if they wanted. Participants completed unrelated tasks and then reported the number of candies they had taken. It was found that those in the upper-class rank condition took more candy than did those in the lower-rank condition. Answer the following questions based on this description. Match the population of interest and the sample with the correct responses.

Why or why not?Select one:No, because the sample is not representative of the population since it consists of only UC Berkeley undergraduates. Yes, because UC Berkeley undergraduates are adults in the United States, so they are part of the population. No, because the sample size is too small. Yes, because it was a random sample. Can the findings of the study be used to establish causal relationships?Select one:No, because the the study is observational. Yes, because the study is observational. No, because the study is an experiment. Yes, because the study is an experiment.
