Q 2. Suppose you read a research article in which the study authors stated that they had collected a sample of 150 adolescents from a single city and found that 22 of them reported being in a gang. What is the population being studied here? What additional pieces of information would you need to know about this sample in order to decide whether to trust this finding as being truly reflective of that population? What characteristics would the sample need to have in order for it to be trustworthy?
