(Step-by-Step) Use the margin of error, confidence level, and standard deviation σ to find the minimum sample size required to estimate an unknown population
Question: Use the margin of error, confidence level, and standard deviation \(\sigma\) to find the minimum sample size required to estimate an unknown population mean \(\mu\).
Margin of error: $121, confidence level: \(95 \%, \sigma=\\) 528$
