The defect rate for a project has histoically been 2.0%. what are the upper and lower control chart limits if you wish to use a sample size of 100 and 3 sigma limits?

Pareto solution The following table shows the defects identified in the final inspection, during a month, in the soft drink bottles, as well as the number of times these have occurred.

30   The upper and lower limits for diving ring diameters made by John's Swimming Co. are 40 and 39 cm., respectively. John took 11 samples with the following average diameters (39, 39.1, 39.2, 39.3, 39.4, 39.5 39.6, 39.7, 39.8, 39.9, 40). Is the process in control?   Select one: a. no, there is a distinguishable pattern in the samples. b. Yes, no diameters exceeded the control limits.  c. no, the range is not in control. d. no, some diameters exceeded the control limits. e. There is not enough information to make a decision.

A manager wishes to build a control chart for a process. A total of five (05) samples are collected with eight (08) observations within each sample. The sample means (X-bar) are; 15.36,14.61,16.36,20.28, and 15.77 respectively. Also, the corresponding ranges are; 10.79, 8.37, 2.81,8.17, and 3.31 respectively. The lower and upper control limits of the R-chart are respectively Select one .a 12.84 ,0.54 None is correct .C 15.25 ,0 .d 14.11,0 Le 12.44,0.94 The correct answer is: 0.94, 12.44
