Thank you so much !! :)

An inspector counted the percent of defectives (out of 100 samples) of a monthly billing statement of a company. Using the following data set, construct a control chart that will describe three sigma of the chance variation in the process. Present your control charts and briefly discuss if the process is in control, your findings, and control limits
