Find the sample size needed to estimate the mean age of movie patrons such that it can be said with 95% confidence that the sample mean is within 2.5 years of the population mean. Assume thato 19.3 years, based on a previous report. Should the sample be obtained from one movie at one theater?The required sample size is 229. (Round up to the nearest integer.)Should the sample be obtained from one movie at one theater?OA. 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.OB. The sample should be obtained from one movie at one theater, because that sample is representative of the population.OC. The sample should not be obtained from one movie at one theater, because that sample could be easily biased. Instead, a simple random sample of the broader population should beobtained.OD. 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.
