Question 1183456: The operations manager of a sugar mill in Chesterville wants to estimate the average size of an order received. An order is measured in the number of pallets shipped overseas. A random sample of 84 orders from customers had a sample mean value of 121.6 pallets. Assume that the population standard deviation is 20 pallets and that order size is normally distributed. Estimate, with 92% confidence, the mean size of orders received from all the mill's customers. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! the half-interval for 92% confidence is z(0.96)*sigma/sqrt(n)
=1.75*20/sqrt(84)
=3.82
(117.78, 125.42) units pallets
