The Denver Police Departmentwants to know if Hispanic residents of Denver believe that the police use racial profiling when malcing traffie stops. A sociologist prepares several questions about the police. The police departmentchooses an SRS of 200 mailing addresses in predominantly Hispanic neighborhoods and sends a uniformed Haspanic police officer to each address to ask the questions of an adult living there. (a) What are the population and the sample? (b) Why are the results likely to be biased even though the sample is an SRS?
