Distinguish Between Specification and Control Limits $99.5 \mathrm { cP }$

Distinguish between specification and control limits.
-Machine oil is used by clothing manufacturers to lubricate and protect sewing
Machines. A company that produces machine oil must ensure that the viscosity of its
Product meets customer requirements. Consequently, the viscosity of every batch of oil
Produced is measured. Suppose that the process mean is 101 cP and the process standard
Deviation is 1.50 cP. What are the limits for a runs chart to be used to see that the process
Remains control? A. $99.5 \mathrm { cP }$ and $102.5 \mathrm { cP }$
B. $96.5 \mathrm { cP }$ and $105.5 \mathrm { cP }$
C. $95.5 \mathrm { cP }$ and $106.5 \mathrm { cP }$
D. $92.5 \mathrm { cP }$ and $110.5 \mathrm { cP }$
E. None of the above
