The standard deviation of the daily demand for a product is an important factor for inventory control for the product Suppose that a pharmacy wants to estimate the standard deviation of the daily demand for a certain antibiotic It is known that the daily demand for this antibiotic follows an approximately normal distribution A random sample of 26 days has a sample mean of 123 orders for this antibiotic with a standard deviation of 10 orders Find a 90 confidence interval for the population standard deviation of the daily demand for this antibiotic Then give its lower limit and upper limit Carry your intermediate computations to at least three decimal places Round your answers to at least two decimal places If necessary consult a list of formulas Lower limit Upper limit X
