Control charts are tools used to determine if a process is under statistical control and hence the stability of the process is evaluated.

17. Management at Webster, in Problem 16, is now concerned as to whether caulking tubes are being properly capped. If a significant proportion of the tubes are not being sealed, Webster is placing its customers in a messy situation. Tubes are packaged in large boxes of 144. Several boxes are inspected, and the following numbers of leaking tubes are found: Sample Tubes...
Boxes of cereals are supposed to weigh exactly 14 oz. Inspectors want to develop process control charts. They take ten samples of six boxes per sample and weigh them. Based on the following computations of the sample means X-bar and the sample ranges, compute the lower and upper control limits and determine whether the process is in control. Use TABLE 10.2 on page 204 of your textbook to find the parameters for control chart limits. Sample X-Bar Range 1 13.8...
A control chart is to be established on a process producing refrigerators. The inspection unit is one refrigerator, and a common chart for nonconformities is to be used. As preliminary data, 16 nonconformities were counted in inspecting 30 refrigerators. (a) What are the three-sigma control limits? (b) What is the α-risk for this control chart? (c) What is the β-risk if the average number of defects is actually 2 (i.e., if c = 2.0)? (d) Find the average run length...
A. Process capability (acceptance sampling) is: B. A process is out of control/ or in control when: C. When does productivity increase/ decrease? D. What action should be taken if a plotted value falls below the lower control limit on a process control chart? E. What are some implicit/ explicit components of a service delivery system? F. Each day for two workweeks (10 days total), George weighs x bags from that day’s production. If the average of the means is...
6) For the process to be capable of meeting design specifications the process capability index must be a- less than one (1.0) b- greater than one (1.0) c less than zero (0.0) d- greater than zero (0.0) 7) We are monitoring a process that has an outcome that is normally distributed with a mean of 100 and a standard deviation of 10. We would use a (n)----- -- to evaluate whether this process's average is remaining in control. a- x-bar...

You want to determine the control lines for a "P" chart for quality control purposes. If the total number of defects from all samples is 2,500, the number of samples is 100, and the sample size is 50, which of the following would be the standard deviation used in developing the control lines? a. .0707 b. .4900 c. .2499 d. .1556 e. .02499 Please show all steps and where all numbers come from if they aren't already given.
8.8. A process is in statistical control with 199 and R-3.5. The control chart uses a sample size of n- 4. Specifications are at 200+8. The quality char- acteristic is normally distributed. (a) Estimate the potential capability of the process. (b) Estimate the actual process capability (c) How much improvement could be made in process performance if the mean could be cen- tered at the nominal value?
