Question

Webster Chemical Company produces mastics and caulking
for the construction industry. The product is blended in
large mixers and then pumped into tubes and capped.
Management is concerned about whether the filling process
for tubes of caulking is in statistical control. The process

of eight tubes were taken, each tube was weighed, and the
weights in Table 3.3 were obtained.

a. Assume that only six samples are sufficient and develop
the control charts for the mean and the range.
b. Plot the observations on the control chart and comment
on your findings.
