Using Drawing Tool to Create Diagrams

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:
