A large manufacturing company in Indianapolis produces valves for the chemical industry.
According to specifications, one particular valve is supposed to have a five-inch opening on the side. Quality control inspectors take random samples of these valves just after the hole is bored.

b) Ordinal level
c) Nominal level
d) Central level
