**Estimating Sample Size for Population Mean**To estimate a population mean, you want to determine an appropriate sample size. Based on previous evidence, we assume the population standard deviation is approximately \( \sigma = 67.3 \). Your goal is to be 98% confident that your estimate will be within 5 units of the true population mean. What should the sample size be?**Sample Size Formula:**\[ n = \]**Instructions:**- Do not round during intermediate calculations.- Use a critical value accurate to three decimal places for precision, which is crucial for system feedback on incorrect answers.
