You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe the population standard deviation is approximately o = 74.5. You would like to be 99.5% confident that your esimate is within 4 of the true population mean. How large of a sample size is required? no Use a critical value accurate to three decimal places, and do not round mid-calculation - this is important for the system to be able to give hints...
