A large bank establishes X-bar and R charts for the time required to process applications for its charge cards. A sample of five applications is taken each day. The first four weeks (20 days) of data give: X-double bar = 16 min s-bar = 3 min R-bar = 7 min Based on the values given, calculate the centerline and control limits for the X-bar and R charts. Mention all the details with the formulae used. (You may use extra sheets of papers (if needed) for showing the details of supporting calculations.)
