You want to obtain a sample to estimate a population mean. Based on previous evidence, you believe thepopulation standard deviation is approximately o = 67.3. You would like to be 98% confident that yourestimate is within 5 of the true population mean. How large of a sample size is required?n =Do not round mid-calculation. However, you are encouraged to use a critical value accurate to threedecimal places - this is important for the system to be able to give hints for incorrect answers.
