The management of a supermarket needs to make estimates of the average daily demand for milk. The following data are available (number of half-gallon containers sold per day): 48, 59, 45, 62, 50, 68, 57, 80, 65, 58, 79, 69.
Assuming that this is a random sample of daily demand, give a 90% confidence interval for average daily demand for milk.
