We want to obtain a sample to estimate a population mean. Based on previous evidence, researchers believe the population standard deviation is approximately σ = 23.9. We would like to be 99.5% confident that the estimate is within 0.2 of the true population mean. How large of a sample size is required? Use 2 decimal places for your critical z value in your calculation. n Hint: Did you round up to the nearest whole number?
