Statistical Quality Control Practice Test 6

1. Process capability ratio C_p cannot be zero.

2. For the calculation of the PCR C_p the process mean must be centered in the case of two-sided specifications.

3. Which of these can be varied?

4. ‘C_p’ and ‘C_pk’ both can’t be used alone to make decisions about the process centering.

5. Which of these can be used to analyze the process capability of the process which has the quality characteristic distributed non-normally?

6. In the design of experiments, the ____________ variables are adjusted first.

7. What is the value of V in the expression of the estimate of C_pm Process Capability Ratio?

8. Which one of these helps us to find both instantaneous and the variability across time variability?

9. The process fallout (in ppm) ___________ with increase in the process capability ratio C_p, for a normally distributed process.

10. If the Lower specification limit for one quality characteristic of one product, is 200, and the mean of the process is estimated to be 264 with an estimate of one sided process capability ratio \(\widehat{C_{pl}}\), what will be the estimate of the process standard deviation?
