###### Question details

Question 5. ABC Manufacturing is also concerned about the
quality of its manufacturing processes. One of the products the
company sells is a bottle of liquid lubricant associated with the
pump product line. ABC's president is familiar with the operations
management concept of control limits (determining an upper and
lower numerical threshold such that a process is considered in
control as long as it stays within those limits).

The president has asked you to take samples of the amount of
liquid in those bottles and determine the upper control limit (UCL)
and lower control limit (LCL) of three standard deviations. He told
you that, based on previous testing, the standard deviation (SD)
for this process is 0.035. You took sample measurements of the
volume of liquid in the bottles, done at different times of the day
(in case that somehow impacted the volume), and this produced the
data in the Sample Measurements Table below:

•Analyze this operations management issue.

•Provide the algebraic equation for the UCL and for the LCL
(using UCL, LCL, M, and SD as variables).

•Calculate and provide the numerical ULC and LCL values.
