Suppose in a large department store, the average number of shoppers is 448, with a standard deviation of 21 shoppers. We are interested in the probability that a random sample of 49 different shoppers will yield a sample mean between 441 and 446 shoppers. Create and attach a normal curve to this document with the following elements: the normal curve, a label of the average number of shoppers, and labels for the sample means of 441 and 446 shoppers. Include all the appropriate symbols.
