Control charts are to be kept on the thickness measurements for a process that rolls 10-gage copper sheets. The current specification in the sheets is 0.1360+0.0020 inch. After collecting 25 samples of n 5 measurements at approximately half-hour intervals, the data were used to determine Σ L:3.421 inches and R.-0.044 inches, with i1 to 25. Assume that the quality...

Samples of n = 6 items are taken from a manufacturing process at regular intervals. A normally distributed quality characteristic is measured and ?̅ and S values are calculated for each sample. After 50 subgroups have been analyzed, we have : ∑ ?? ̅50 ?=1 = 1000 and ∑ ?? 50 ?=1 = 75 (a) Compute control limits for the ?̅ and S control charts. (b) Assume that all points on both charts plot within the control limits. What are...

Samples ofn-6 items each are taken from a manufacturing process at regular intervals. A normally distributed quality characteristic is measured, and X and S values are calculated for each sample. After 50 samples, we have 50 50 X, = 1000 S,-75 and a) Compute the control limits for the Xand S control charts. b) Assume that all points on both control charts plot within the control limits computed in part (a). What are the natural tolerance limits of the process?...

A company packages a bulk product in bags with a 50-pound label weight. During a typical day's operation of the fill process, 22 subgroups of five bag fills are observed. Using the observed data, 1 and Rare calculated to be 52.9364 pounds and 1.6818 pounds, respectively. When the 22 I's and 22 Rs are plotted with respect to the appropriate control limits, the first 6 subgroups are found to be out of control. We found that the elimination of a...

As part of the process for improving the quality of their cars, Toyota engineers have identified a potential improvement to the process that makes a washer that is used in the accelerator assembly. The tolerances on the thickness of the washer are fairly large since the fit can be loose, but if it does happen to get too large, it can cause the accelerator to bind and create a potential problem for the driver. (Note: This part of the case...
