The J H group's assembly unit has decided to use a p-Chart to monitor the proportion of defective castings produced by their production process. The control limits on these charts will be designed to include 97% of the sample proportions when the process is In Control. The quality control manager randomly samples 200 castings at 10 successively selected time periods and counts the number of defective castings in the sample. Sample Defects 1...............7 2...............12 3...............8 4...............14 5...............8 6...............9 7...............8 8...............8...

Smith and Johnson Industries has decided to use a p-Chart with 3-sigma control limits to monitor the proportion of defective galvanized pipes produced by their production process. The quality control manager randomly samples 150 galvanized pipes at 16 successively selected time periods and counts the number of defective galvanized pipes in the sample. Step 1 of 8: What is the Center Line of the control chart? Round your answer to three decimal places. Step 2 of 8: What value of...

4) Now that Continental can detect more defects before the Silver Box is shipped, I decided process Improvements in its circuit board fabrication department would further improve quality. So, for one process they collected the following data this morning to set up a mean control chart. Since the process mean is unknown, estimate the mean and find the UCL and LCL for a 3-sigma mean control chart using this morning's samples. Sample 1 - 24, 24, 25, 22, 21 Sample...

7.30 A quality-control inspector rejects any shipment of printed circuit boards whenever 3 or more defectives are found in a sample of 100 boards tested. Find the (1) expected number defective and (2) the probability of rejecting the shipment when the proportion of defectives in the entire shipment is (a) Proportion of Defectives-0.01 Expected Number Defective- Probability of Rejecting the Shipment (b) Proportion of Defectives-0.05 Expected Number Defective- Probability of Rejecting the Shipment- (c) Proportion of Defectives 0.1 Expected Number...

A company that makes car parts. The company control its production process by periodically taking a sample of 100 units from the production line. Each product is inspected for defective features. Control limits are developed using three standard deviations from the mean as the limit. During the last 12 samples taken, the proportion of defective items per sample was recorded as follows: 0.01 0.01 0.0 0.04 0.01 0.01 0.00 0.01 0.02 0.02 0.03 0.03 a. Determine the mean proportion defective,...

5. You are the quality control manager of a series of assembly line operations that produce small car parts. From historical records, you realize that the chance of producing a defective part is 6 %. It is believed that the appearance of one bad part on the line has no impact on the status of the parts following it on the line. Of the next ten parts coming off the assembly line, what's the probability...

5-7. A manufacturing company employs two devices to inspect output for quality control purposes. The first device is able to accurately detect 99.4% of the defective items it receives, whereas the second is able to do so in 99.7% of the cases. Assume that four defective items are produced and sent out for inspection. Let X and Y denote the number of items that will be identified as defective by inspecting devices 1 and 2, respectively. Assume that the devices...
