***Sample Size Calculation for Political Polling***A political candidate has asked his/her assistant to conduct a poll to determine the percentage of people in the community that supports him/her. The candidate wants an 8% margin of error at a 99% confidence level. What size of sample is needed? *Be sure to round accordingly.***Calculation Requirement:**The candidate would need to survey [blank space] people in the community to be within an 8% margin of error at a 99% confidence level. --- *Note: Sample size calculation is crucial for achieving desired accuracy in statistical analysis. The margin of error and confidence level directly influence the sample size needed to ensure the poll's reliability.*

The random variable X follows binomial distribution. The margin of error is 0.08. The level of…
