• Engineering technologists use statistical information and control charts to track their performance on a variety of indicators. Recently one engineering technologist manager was asked whether their team is capable of maintaining scores between 8 and 10 (on a scale of 1 to 10, with 10 being the highest level) for “overall professionalism.” The most recent data has a mean of 8.624, a standard deviation of 1.446, and n = 10.

• Determine and share: Cp, Cpk Interpret the indices

Statistical process control explain the types of control charts available for analysis, the basis under which their limits are defined and change, the types of analysis that lead to decisions of controlled or not-controlled, and the types of risks associated with different sample sizes and limit settings. In particular, describe what it means statistically to declare that a process is not in control.

Statistical process control charts: A. display upper and lower limits for process variables or attributes and signal when a process is no longer in control. B. display the measurements on every item being produced. C. are a graphic way of classifying problems by their level of importance, often referred to as the 80-20 rule. D. indicate to the process operator the average outgoing quality of each lot. E. indicate to the operator the true quality of material leaving the process.

A statistical program is recommended. The National Football League (NFL) records a variety of performance data for individuals and teams. To investigate the importance of passing on the percentage of games won by a team, the following data show the conference (Conf), average number of passing yards per attempt (Yds/Att), the number of interceptions thrown per attempt (Int/Att), and the percentage of games won (Win%) for a random sample of 16 NFL teams for one full season. Team Conf Yds/Att...

Statistical Process Control is a critical part of tracking performance, and evaluation of process capability is an important element to track the need to closely monitor. Using the table below and the attached X-bar, S charts, determine the process capability indices for the process (Cp, Cpk), and evaluate whether the process is capable for average surface roughness (Ra) for the inner diameter of tubing. If not, what change(s) should be made next to get Cpk ≥ 1.33? The specification requires...
