special cause variation is:

select one:
a. variation outside normal limits
b. expected random fluctuation
c. controlled by dead band
d. always acceptable

question 5 not yet answered points out of 1.00 flag question

which best defines a process in manufacturing?

select one:
a. a set of steps that produces a result or creates a product
b. any piece of equipment used in production
c. a single chemical reaction only
d. a safety rule

Explanation:

Define special cause variation

Process variation is divided into common cause and special cause variation. Common cause variation is the inherent, expected random fluctuation in a stable process. Special cause variation refers to non-random, assignable events that cause the process to drift outside its normal statistical control limits. Therefore, option (a) is the correct definition.

Define a manufacturing process

In industrial manufacturing, a process is broadly defined as a systematic sequence of operations or steps. These steps transform raw materials, energy, and information into a finished product or a desired physical result. Option (a) accurately captures this fundamental definition, whereas the other options describe equipment, specific chemical reactions, or safety rules.

Answer:

Question 4

• a. Variation outside normal limits (Correct answer)

• c. Controlled by dead band
• d. Always acceptable

Question 5

• a. A set of steps that produces a result or creates a product (Correct answer)
• b. Any piece of equipment used in production
• c. A single chemical reaction only
• d. A safety rule
