Twelve samples, each containing five parts, were taken from a
process that produces steel rods at Emmanual Kodzi's factory. The
length of each rod in the samples was determined. The results were
tabulated and sample means and ranges were computed.
Refer to Table S6.1 - Factors for computing control chart limits
(3 sigma) for this problem.

A quality controller measures tensile stress (kg per
cm2) of a metal fastener in thirty samples of size 7.
The following is a summary of the collected data.
i=1i=30xi = 12,780 and
i=1i=30Ri=1530
where xi = average
and Ri = range of sample i. The quality
controller finds that R chart is in control and now wants to
construct x-bar R chart.
Determine an unbiased estimate of the standard deviation of
tensile stress of metal fasteners.

Pioneer Chicken advertises "lite" chicken with 30% fewer
calories than standard chicken. When the process for "lite"
chicken breast production is in control, the average chicken
breast contains 420 calories, and the standard deviation in
caloric content of the chicken breast population is 20 calories.
Pioneer wants to design an x overbar-chart to monitor the caloric
content of chicken breasts, where 25 chicken breasts would be
chosen at random to form each sample. a) What are the lower and
upper...
