Determine whether the following statement is true or false. Explain. When obtaining a stratified​ sample, the number of individuals included within each stratum must be equal. Choose the correct answer below. A. True. Sampling the same number of people from each stratum will result in a sample that is representative of the population at a lower cost than a simple random sample. B. False. When taking a stratified​ sample, a simple random sample is drawn from one stratum at random. All other strata will not be included in the sample. C. False. A stratified sample is constructed by successively selecting a stratum at random and then selecting a random individual from within that stratum. With this​ process, it is unlikely that all strata will be sampled from the same number of times. D. False. Within stratified​ samples, the number of individuals sampled from each stratum should be proportional to the size of the strata in the population.
