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.

The percent defective for parts produced by a manufacturing
process is targeted at 4%. The process is monitored daily by taking
samples of sizes n = 160 units. Suppose that today’s sample
contains 14 defectives. Determine a 88% confidence interval for the
proportion defective for the process today.

A manufacturing process produces steel rods in batches of 1,700.
The firm believes that the percent of defective items generated by
this process is 5.4%. a. Calculate the centerline, the upper
control limit (UCL), and the lower control limit (LCL) for the p⎯⎯
chart. (Round your answers to 3 decimal places.) b. An engineer
inspects the next batch of 1,700 steel rods and finds that 6.5% are
defective. Is the manufacturing process under control?

Problem 3) Jane Hochkiss, director of production, has decided to
record the number of defective labels in random daily samples on
control charts. Jane estimates that 1.5 percent loose labels is
typical when the labeling process is in control. Twelve daily
samples, each consisting of 200 pairs of jeans, were selected and
examined. The number of defective labels found in each sample is
shown below.
