Question 25 (1 point) Though only seven averages and range values are available, the engineers studying the olive bottle filling process have decided to create X-bar and R charts for the samples measuring the air gap in the bottle. Calculate the centerline and control limits for the following information: Sum of X-bars = 339.4 Sum of R's = 3.4 m = 7, n = 5 Using the data from question 20, what is the LCL value for the Range chart?

A control chart using standard deviation is more accurate than a range control chart When the sample size is less than 10, a control chart using standard deviation should be used rather than a range control chart Question 27 (2 points) Manufacturing medical devices requires the ability to meet close tolerances. For a particularly difficult machine setup, the manufacturing engineer conducted two runoffs for an injection molding machine. The manufacturing engineer would like to know with 95% confidence, the interval values for the population mean for the second runoff?

Process measures relate to both organizations and their customers and are tied to organizational objectives and what the customer hopes to achieve by doing business with the organization.
