A six-sigma green belt candidate finds P/Tratio of his gauge as 0.632. The gauge hasno bias. He tried improving his gaugeprecision, but failed to do so. He plans to useaverages of repeated measurements in hisquality improvement project. How manyrepeated measurements does he need tomake on a part to have a P/T ratio of 0.200based on the measurement averages?Answer:

Explain the concept of the control chart and identify out-of-control signals on a control chart. Within your answer, explain what you would do if you were a Quality Manager making your rounds throughout the plant and found a control chart that indicated an out-of-control situation.
Do control charts assist in monitoring quality as conformance or quality as improvement?
A quality engineer has a manufacturing specification (in cm) of 0.25 plus or minus 0.05 Historical data indicates that if the quality characteristic takes on values larger than 0.3 cm or smaller than 0.2 cm, the product fails and a cost of $90 is incurred.

Boston Electric Generators has been getting many complaints from its major customer, Home Station, about the quality of its shipments of home generators. Daniel Shimshak, the plant manager, is alarmed that a customer is providing him with the only information the company has on shipment quality. He decides to collect information on defective shipments through a form he has asked his drivers to complete on arrival at customers' stores. The forms for the first 287 shipments have been turned in. They show the following over the past 8 weeks: Week No. of Shipments No. of Shipments with Defects 1 23 10 2 31 11 3 32 12 4 39 13 5 35 12 6 40 14 7 41 14 8 46 17 This exercise contains only part a. a) Using the point drawing tool eight times, develop a scatter diagram using total number of shipments and number of defective shipments. Part 2
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.
The smallest defect in a computer chip will render the entire chip worthless. Therefore, tight quality control measures must be established to monitor these chips. In the past, the percent defective at Chieh Lee's Computer Chips has been 1.5%. The sample size is 1,000. Determine upper and lower control chart limits for these computer chips. Use z = 3. Upper Control Limit (UCL) = (round your response to four decimal places). Lower Control Limit (LCLp) = (round your response to four decimal places).
