K 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. OA. No. It would be nearly impossible to get exactly 500 males and 500 females from every country by random chance. OB. Yes. It is likely that 500 males and 500 females from every country were interviewed by random chance. OC. No. They are using a census rather than a simple random sample. OD. 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? OA. A stratified sample, stratified by whether the respondent is male or female. OB. A multistage sample, which uses a variety of sampling methods together. OC. Systematic sampling, in which individuals are selected systematically. O D. This design is a cluster sampling because the population is split into representative clusters.
