Textbook Question
Chapter 1, Problem 1.27P
A manufacturer wants to quantify the expected average fuel mileage of a product line of automobiles. It decides that cither it can put one or more cars on a chassis dynamometer and run the wheels at desired speeds and loads to assess this, or it can use drivers and drive the cars over some selected course instead, (a) Discuss the merits of either approach, considering the control of variables and identifying extraneous variables, (b) Can you recognize that somewhat different tests might provide answers to different questions? For example, discuss the difference in meanings possible from the results of operating one car on the dynamometer and comparing it to one driver on a course. Cite other examples.
(c) Do these two test methods serve as examples of concomitant methods?

Q.49 A person operates a machine that makes capacitors. He has been advised to keep
the track of the percentage defectives at his work center. He knows that this type of
process, they expect about 4% defectives plus or minus some chance variation. He
wishes to initially construct a control chart for defectives. He has prepared ten daily
samples of hundred capacitors each.

The data shown in Table 1 are the deviations from nominal diameter for holes drilled in a
carbon-fiber composite material used in aerospace manufacturing. The values reported are
deviations from nominal in ten-thousandths of an inch.
(a) Set up and R charts on the process. Is the process in statistical control?
(b) Estimate the process standard deviation using the range method.
