Find the sample size needed to estimate the mean age of movie patrons such that it can be said with 98% confidence that the sample mean is within 2 years of thepopulation mean. Assume that o = 19.3 years, based on a previous report. Could the sample be obtained from one movie at one theater?The required sample size is. (Round up to the nearest integer.)C Couldthe sample be obtained from one movie at one theater?A. The sample should be obtained from one movie at one theater, because that sample is representative of the population.B. 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 thebroader population should be obtained.C. 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 broaderpopulation should be obtained.OD. 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 broaderpopulation should be obtained.

Here, Confidence level is 0.98, E= 2, and σ=19.3. Thus, α=0.02=1-0.98.
