1. A textile company monitors its process by counting the number of defects in the bolts of cloth it produces. To establish its control chart limits, a random sample of 20 bolts of cloth was selected and the average number of defect per bolt calculated. If the sample average was 25 defects per bolt, then the 3-sigma upper and lower control chart limits for this process would be

UCL = 20; LCL = 5

UCL = 45; LCL = 0

UCL = 40; LCL = 10

UCL = 25; LCL = 15

2. Design specifications reflecting customer requirements for a product are known as

control limits

capability indices

natural variability

Tolerances

3. When the process capability ratio is less than 1.0

the process is capable of producing within the design specification all the time

the process is not capable of producing within the design specification all the time

the tolerance range and the process range are directly related to if the Mets win the World Series

all of the above

4. The natural variation of a process relative to the variation allowed by the design specifications is known as

process capability

design tolerances

control limits
