A. Choudhury's bowling ball factory in Illinois makes bowling balls of adult size and weight only. The standard deviation in the weight of a bowling ball produced at the factory is known to be 0.39 pounds. Each day for 24 days, the average weight, in pounds, of 9 of the bowling balls produced that day has been assessed as follows: Day Average (lb.) Day Average (lb.) Day Average (lb.) Day Average (lb.) 1 9.9 7 9.9 13 9.9 19 10.1...

The upper and lower control limits on control charts are usually set at a distance of +/- three times the standard deviation from the center line of the control chart. Use independent research to find the reasons why. Make sure you use the concept of type I and type II error in your discussion. Under what circumstances might a manager consider the use of limits at two times the standard deviation. What should the manager keep in mind when setting...

Product filling weights are normally distributed with a mean of 365 grams and a standard deviation of 19 grams. a. Compute the chart upper control limit and lower control limit for this process if samples of size 10, 20 and 30 are used (to 2 decimals). Use Table 19.3. For samples of size 10 UCL =| LCL For a sample size of 20 UCL = LCL For a sample size of 30 UCL = LCL = b. What happens to...

A. Determine the fraction of nonconforming product control chart upper limit when the standard given is 0.01 proportion of nonconforming B. A series of 33 samples of size 100 have been produced. The total number of defectives in the samples is 51. Determine the proportion of defective product C. A series of 20 samples of size 4 has been drawn from a project. The measure of interest has an average of 20.0443, and the average range within the samples is...

The U Chart versus the C Chart The C chart is used when a single
unit will be examined for nonconformities at each time point. The U
chart is used when a number of units will be sampled at each time
point, and a per unit average number of nonconformities will be
obtained. U Chart Formulas Suppose we have k samples, each of size
ni. Let Di represent the total number of nonconformities in the i
th sample. Formulas for...
