Description
Use the Standard Deviation Control Chart X-Bar S. Review the details for this chart in the textbook. Subgroup = 20. Each shipment has 500 observations. 1. Click on the question and click Begin to download the assigned dataset of two shipments, each identified with a Tracking Number. 2. Analyze the two assigned shipments. 3. For each shipment: a.Run descriptive statistics and set-up and run control charts (X-Bar and S). b. Calculate the percentage of total time the temperature is outside the specification limits. Specification limits are 32-41 degrees Fahrenheit. c. Using z-scores, predict the percentage of readings that will be out of specification in the future and compare to b. d. Determine the process capability (Cp and Cpk).
