Question

A production manager knows that 8.5% of components
produced by a particular manufacturing

process have some defect. Eight of these components, whose
characteristics can be assumed

to be independent of each other were examined.

a. Write the distribution function in terms of ? and x.

b. What is the probability that none of these components has a
defect?

c. What is the probability that two of the components have a
defect?

d. What is the probability that between two and seven components
have a defect?

e. What is the probability that at most three of the components
have a defect?

f. What is the probability that at least two of these components
have a defect?

g. What is the expected defective components and the coefficient of
variation?

Answer #1

A production manager knows that 95% of components produced by a
particular manufacturing process have no defect. Six of these
components selected randomly and examined,
What is the probability that two of these components
havedefect?
What is the probability that at least four of these components
have a defect?
What is the expected number of defective
sets?
Interpret the result of all three parts of this question.

Exercise 12.8.1: Probability of manufacturing defects. The
probability that a circuit board produced by a particular
manufacturer has a defect is 1%. You can assume that errors are
independent, so the event that one circuit board has a defect is
independent of whether a different circuit board has a defect. (a)
What is the probability that out of 100 circuit boards made exactly
2 have defects? (b) What is the probability that out of 100 circuit
boards made at least...

A manufacturer of window frames knows from long
experience that 5% of the production will have some type of minor
defect that will require adjustment. What is the probability that
in a sample of 20 window frames
None will need adjustment
At least one will need adjustment
More than two will need adjustment

Some LCD panels have stuck or "dead" pixels that have defective
transistors and are permanently unlit. If a panel has too many dead
pixels, it must be rejected. A manufacturer knows that, when the
production line is working correctly, the probability of rejecting
a panel is .07 of every 500 panels produced. (a) what is the
probability that they will reject 37 or more screens in one
production day? (b) if the production manager told you that the
distribution for...

1) What are some indicators that there are assignable
causes for variation in a process?
I.Process capability.
II. Data patters outside of the control limits.
III. Data patters within the control limits.
IV. Points randomly falling above and below the control chart
center line.
a.
II and III
b.
II, III, IV
c.
I, II, IV
d.
I, II, III, IV
2) The best quantitative tool to determine the cause for
variation in a process is:
a.
ANOVA
b.
Correllation...

CASE STUDY – Jacobson Carpet Company
In January 2002, Ms. Mary Lewis was preparing to meet with Mr.
Carpenter, President of Jacobson Carpet Company.
Ms. Lewis assumed that the meeting was related to the recent

to the President, she knew from experience that this type of
meeting often resulted in a project to be studied. Her
expectation was confirmed as soon as Mr. Carpenter began to
inform her of the...
