Question content area bottom Part 1 The required sample size is: Part 2 Could the sample be obtained from one movie at one theater? A. The sample should not be obtained from one movie at one theater, because that sample could be easily biased. Instead, a stratified sample of the broader population should be obtained. B. The sample should not be obtained from one movie at one theater, because that sample could be easily biased. Instead, a cluster sample of the broader population should be obtained. C. The sample should be obtained from one movie at one theater, because that sample is representative of the population. D. The sample should not be…arrow_forward
