A manufacturing company produces cylindrical tubes for engines that are specified to be 1.20 centimeters thick. As part of the company’s statistical quality-control effort, random samples of four tubes are taken each hour. The tubes are measured to determine whether they are within thickness tolerances. Shown here are the thickness data in centimeters for nine samples of tubes. Use these data to develop an x¯ chart line graph and an R chart line graph

A manufacturing company produces cylindrical tubes for engines
that are specified to be 1.20 centimeters thick. As part of the
company’s statistical quality-control effort, random samples of
four tubes are taken each hour. The tubes are measured to determine
whether they are within thickness tolerances. Shown here are the
thickness data in centimeters for nine samples of tubes. Use these
data to develop an x¯ chart and an R chart.

A company manufactures cylindrical paint cans with open tops
with a volume of 17,000 cubic centimeters. What should be the
dimensions of the cans in order to use the least amount of metal in
their production? HINT [See Example 4.] (Round your answer to two
decimal places.)

Hawkins Manufacturing Company produces connecting rods for 4-
and 6-cylinder automobile engines using the same production line.
The cost required to set up the production line to produce the
4-cylinder connecting rods is $1800, and the cost required to set
up the production line for the 6-cylinder connecting rods is $3300.
Manufacturing costs are $15 for each 4-cylinder connecting rod and
$20 for each 6-cylinder connecting rod. Hawkins makes a decision at
the end of each week as to which...

Fame Company manufactures engines. Fame produces all the parts
necessary for its engines, except for one electronic component,
which is purchased from two local suppliers: Hydra International
and Parable Company. Both suppliers are reliable and rarely deliver
late. Hydra sells the component for $12.00 per unit, while Parable
sells the same component for $10.00. Fame purchases 80% of its
components from Parable because of the lower price it offers. The
total annual demand is 95,000 units.

A Packaging Company produces boxes out of cardboard that has a
specified weight of 30 oz. It is known that the weight of a box is
normally distributed with standard deviation σ =1.3 oz. A random
sample of 16 boxes yielded a sample mean of 30.7 oz. At 5% level of
significance, test the claim that the mean weight of a box is more
than 30 oz.
State what is given, what are the hypothesis, what is the test
statistic,...

The Packaging Company produces boxes out of cardboard and has a
specified weight of 8 oz. A random sample of 20 boxes cans yielded
a sample mean of 7.5 oz. Given the data's distribution is normally
distributed and standard deviation is 1.4 oz, for a 95% confidence
interval, what is the lower confidence limit? What is the standard
error? What is the estimated margin of error?

A company produces small engines for regular cars, and it
decides to produce a larger engine that will be used for trucks. As
the company has never produced this kind of engine, a specific
piston ring size needs to be purchased in order to produce the new
engine. Assume that you are responsible for the procurement of that
piston ring from three different suppliers. The inside diameter
length of the piston has been determined as a quality
characteristic with a...
