3. A pharmacy is using X bar and R charts to record the time it takes to fill a prescription after the customer has turned in or called in the prescription. Each day, the pharmacy records the times it takes to fill six prescriptions. During a 30-day period, the hospital obtained the following values: X double bar = 20 minutes; R bar = 4 minutes. The upper and lower specifications are 23 minutes and 13 minutes respectively. What is the value of Cpk, to two decimal places?

A large bank established 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 bar 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.

x bar and R control Charts A quality control inspector at the Company B has taken twenty-five samples with four observations each of the sample weight (g). The data are shown in the table. Construct x bar and R control charts for these data. Identify any out-of- control points. Assume these points (if any) are assignable. Remove them and recalculate the control limits. Construct the revised x bar and R control charts. Submit data (spreadsheet) and charts. Comment on the...

1. Why are X-bar and R-Charts used together? Please Explain. 2. The principal focuses and methods of the pioneers of scientific management, what are they?(as represented by Henry Gantt, Frederick Taylor, Frank Gilbreth,etc.). In your words, how is the modern total quality management method different from the above?

A tomato farmer has been using an X-bar and R chart to control the yield per plant on her highly-mechanized farm. The yield is table over time in both variability and location. The X-bar chart has a centerline value of 10.50 pounds and the upper control limit is 14.20 pounds. Find the value of the lower control limit of the X-bar chart? Find the value of the upper and lower one-sigma and two-sigma zones of the X-bar chart? Find the...
