Textbook Question
Chapter 3, Problem 52P
The Shuler Motor Mile is a high-volume discount car dealership that stocks several different makes of cars. It also has a large service department. The dealership telephones six randomly selected customers each week and conducts a survey to determine their satisfaction with the service they received. Each survey results in a customer satisfaction score based on a 100-point scale, where 100 is perfect (and what the dealership ultimately aspires to). Following are the survey results for three months:
- a. Develop an x-chart to be used in conjunction with an R-chart using 3σ limits to monitor the level of customer satisfaction at the dealership and indicate if customer satisfaction is being accomplished on a continuing basis.
- b. The dealership would like to achieve an average customer satisfaction score of 95 (±3); is the service department capable of this?

Chart and Regression analysis :
What does the intercept predict?
X: C16 (number of cars on the sales lot) versus Y: C17 (cars sold per day)
Equation: y=2.9x + 14.5
Slope:2.9
Intercept:14.5
Does the intercept mean the intercept is 14.5 means that the cars sold per day( Y) predicted number of cars on sale lot(X) to be 14.5, but this intercept has no meaning. So, I will not use to predict cars sold per day?
ASQ (The American Society for Quality) Defines a Six Sigma project as: Six Sigma is a method for reducing variation in manufacturing, service, or other business processes. Six Sigma projects measure the cost benefit of improving processes that are producing substandard products or services. Whether in manufacturing or service industries, such projects quantify the effect of process changes on delays or rework. The goal of each successful Six Sigma project is to produce statistically significant improvements in the target process; over time, multiple Six Sigma projects produce virtually defect-free performance. The Six Sigma Black Belt project is one that uses appropriate tools within a Six Sigma approach to produce breakthrough performance and real financial benefit to an operating business or company. The tools are generic. It is the structure of the project and the associated process (improvement model) that distinguish a Black Belt project from other similar quality improvement…
