A new engineer joins the company and skeptical about OMI's historical data of daily production process that it is ~ N (700, 50). He takes a random sample of 64 daily production from last nine month's production and he calculates the sample mean as 685 and sample standard deviation as 56. He wants to calculate a 95 % confidence interval for his estimation of daily production mean before he goes to his manager and questions current assumptions. What are the confidence limits
