An internet company conducts a global consumer survey to help multinational companies understand different consumer attitudes throughout the world. Within 30 countries, the researchers interview 1000 people aged 13-65. Their samples are designed so that they get 500 males and 500 females in each country. Complete parts a and b below a) Are they using a simple random sample? Explain. O A. No. They are using a census rather than a simple random sample. O B. Yes. It is likely that 500 males and 500 females from every country were interviewed by random chance. O C. No. It would be nearly impossible to get exactly 500 males and 500 females from every country by random chance. O D. Yes. The population is split into representative clusters; therefore, it is a simple random sample. b) What kind of design do you think they are using? O A. A multistage sample, which uses a variety of sampling methods together. O B. This design is a cluster sampling because the population is split into representative clusters. OC. Systematic sampling, in which individuals are selected systematically. O D. A stratified sample, stratified by whether the respondent is male or female.
