You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately σ=67.6σ=67.6. You would like to be 99.5% confident that your esimate is within 0.1 of the true population mean. How large of a sample size is required? n = Do not round mid-calculation. However, use a z value accurate to three decimal places — this is important for the system to be able to give hints for incorrect answers.
