This is confusing me


1. Develop a control chart for the following process and proportion of defective products:
a. Historical π = .2 defective products per day
b. A sample conducted on Friday of 600 items revealed a p = .25.
c. The boss wants to know if the process is out of control or not


Is the historical the process mean? Help would be much appreciated!
