A marketing expert for a particular chain of restaurants is planning a survey in which 510 people will be randomly selected from each age​ group: 10-19,​ 20-29, and so on.       What type of sampling is​ used?     Convenience sampling   Simple random sampling   Systematic sampling   Stratified sampling   Cluster sampling Is the procedure likely to yield a representative sample or a biased​ sample? Explain why.     A. The procedure is likely to yield a representative sample because it covers every age group.   B. The procedure is likely to be biased because people from those age groups are not evenly distributed throughout the population.   C. The procedure is likely to yield a biased sample because younger people​ don't know what they want and should be studied separately.   D. The procedure is likely to be representative because 510 people from each age group form a large sample size.
