Question
Please explain why choosing the below. Thank you!
96. In the design of a controlc hart for process variation, when sample sizes are greater than 25, the centerline of the control chart will be the mean of several preliminary samples
True or False
97. The term manage is not on eof the steps in the DMAIC acronym.
True or False
98. Primary cause variation is the variation of most concern in six sigma
True or false
99.Consider that an on=line order form contains 12 fields of information. To determine the DPMO 20, forms are sampled, and 14 defects uncovered. The DPMO is ____
a.) 700000
b.) 0.0583
c.) 58333
d.) none of the above
100. NP and P charts are used to monitor discrete data
True or False
Explanation / Answer
Solution
96) True,The center line of the x-chart is plotted at the level of the sample mean (average) of the k subgroup means.
97) Flase, DMAIC is an abbreviation of the five improvement steps it comprises: Define, Measure, Analyze, Improve and Control
98) False, Special Cause Variations always cause the process to go out of control and hence is the variation of most concern.
99) DPMO = 1,000,000*(defects/(number of units*opportunities) = 1,000,000*((14/20*12)) = 58333
option (c)
100) True, NP and P charts are used to monitor discrete data
