Question

43. Honda wants to monitor the number of blemishes (scratches, blisters, etc.) on the fenders of its cars using a statistical process control chart. The most appropriate type of SPC chart is:

a. X-bar.

b. R-bar chart.

c. CpK chart.

d. C-chart.

e. Q-chart

44. In the context of designing control charts, which of the following is true of a sample size?

a. A large sample allows small changes in process characteristics to be detected with higher probability than a small sample size.

b. A small sample is used to detect process shifts of two standard deviations or smaller.

c. A large sample size is desirable to keep the cost associated with sampling low.

d. A small sample size provides greater degrees of statistical accuracy in estimating the true state of control than a large sample size.

e. A small sample allows for medium-sized changes in process characteristics to be detected with a stationary probability than a small sample size.

45. Which of the following is true of special cause variation?

a. It cannot be explained or understood.

b. It occurs sporadically and can be prevented.

c. It cannot be detected using statistical methods.

d. It accounts for about 80 to 95 percent of the observed variation in a process.

Explanation / Answer

43. The answer is given below:

d. C-chart

Honda can use on C chart of statistical process control chart, as where the defects and mistakes can be found.

44. The answer is given below:

a. A large sample allows small changes in process characteristics to be detected with higher probability than a small sample size.

In the design control chart it improves and strengthen the business and reduce the frequency of failure by allowing the large sample to detect the changes on high probability.

45. The answer is given below:

d. It accounts for about 80 to 95 percent of the observed variation in a process.

The variation is caused by known factors from environmental condition or input parameters.
