Question
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 25 days has a sample mean of 121 orders for this antibiotic with a standard deviation of 10.3 orders. Find a 99%
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.)
