A hotel chain wants to estimate the average number of rooms rented daily in each month. The population of rooms rented daily is assumed to be normally distributed for each month with a standard deviation of 24 rooms.

During January, a sample of 16 days has a sample mean of 48 rooms.

Using this information the upper limit (to two decimal places) of a 95% cofidence interval estimate for the population mean is?

estion 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 23 days has a sample mean of 125 orders for this antibiotic with a standard deviation of 10.1 orders. Find a 95%...
