A manager wants to build 2-sigma x-bar control limits for a process. The target value for the mean of the process is 10 units, and the variance of the process is 36. If 9 units are to be taken in each sample, what will be the lower and upper control limits, respectively? Select one: a. [2,18] b. [6,16] c. [8.66,11.34] d. [8,12] e. [6,14]

A manager wishes to build a 3-sigma range chart for a process. The sample size is five, the mean of sample means is 16.01, and the average range is 5.3. From Table S6.1, the appropriate value of D3 is 0, and D4 is 2.115. What are the UCL and LCL, respectively, for this range chart? 33.9 and 11.2 6.3 and 0 11.2 and 0 33.9 and 0 which is the correct answer?

The Operations manager at a large widget factory is complaining that since the company has changed to a cheaper supplier for one of the raw materials used for widgets, the quality of their widget has changed. In fact, he has one of the final widgets that has a strength testing below their spec. The new operations employee had previously taken 5 samples each week over a 10-week period, and logged the data in the chart below. Calculate upper and lower...
