Steps for appropriate disposition of suspect material/products is usually found in
Reaction Plan
31
What happens in the norming stage

32
In a crossed-array designed experiment, it is found that there are no significant control-by-noise interactions. This means
There is no robust design problem
33
In an acceptance sampling plan, how does the probability of acceptance change for a given fraction nonconforming as the acceptance number increases
Probability of acceptance increases
34
What is the first step to take when prioritizing corrective action?

37
What describes the phenomenon in which high-order interactions are negligible and a system is dominated by the main effects and low-order interactions:
Sparsity-of-effects principle
38
If events A and B are mutually exclusive then probability is equal to
A+B
39
If events A and B are independent then probability of both occuring is equal to
A x B

Philip Crosby
41
In what way does the official definition of the base unit of mass differ from the definitions of other base units?
Its definition is in terms of a physical artifact
42
If a process it out of control, it is desirable to
