A computer memory manufacturer specifies that its memory chip stores data incorrectly an average of 6.3 out of 10 million cycles with a standard deviation of 0.48. A batch of 30 chips your company ordered stores data incorrectly an average of 6.9 times per 10 million cycles. a. Does it seem reasonable that your 30 chips are a random sample from a population with the specifications given by the computer memory manufacturer? Use a = 0.052 tail. b. What is the critical value of z?

A computer manufacturer estimates that its line of minicomputers
has, on average, 8.6 days of downtime per year. To test this claim,
a researcher contacts seven companies that own one of these
computers and is allowed to access company computer records. It is
determined that, for the sample, the average number of downtime
days is 5.2, with a sample standard deviation of 1.1 days. Assuming
that number of downtime days is normally distributed, test to
determine whether these minicomputers actually...

A computer chip manufacturer is considering expanding production
to meet possible increases in demand. The company's alternatives
are to construct a new plant, expand the existing plant, or do
nothing in the short run. It will cost them $1 million to build a
new facility and $600,000 to expand their existing facility. The
market for this particular product may expand, remain stable, or
contract. The marketing department estimates the probabilities of
these market outcomes as 0.30, 0.50, and 0.20, respectively....

2.A computer manufacturer estimates that its line of
minicomputers has, on average, 8.5 days of downtime per year. To
test this claim, a researcher contacts seven companies that own one
of these computers and is allowed to access company computer
records. It is determined that, for the sample, the average number
of downtime days is 5.1, with a sample standard deviation of 1.5
days. Assuming that number of downtime days is normally
distributed, test to determine whether these minicomputers actually...

Suppose a computer chip manufacturer rejects 1% of the chips
produced because they fail presale testing. Assume the bad chips
are independent. Complete parts a through d below
a) Find the probability that the third chip they test is the
first bad one they find. The probability is __________
b) FInd the probability they find a bad one within the first 11
they examine _________
c) Find the probability that the first bad chip they find will
be the fourth...

A manufacturer of computer memory chips produces chips in lots
of 1000. If nothing has gone wrong in the manufacturing process, at
most 5 chips each lot would be defective, but if something does go
wrong, there could be far more defective chips. If something goes
wrong with a given lot, they discard the entire lot. It would be
prohibitively expensive to test every chip in every lot, so they
want to make the decision of whether or not to...

A computer chip manufacturer spent $2,540,000 to develop a
special-purpose molding machine. The machine has been used for one
year and is expected to be obsolete after an additional 3 years.
The company uses straight-line (SLN) depreciation for this
machine.
At the beginning of the second year, a machine salesperson offers a
new, vastly more efficient machine. This machine will cost
$2,040,000, reduce annual cash manufacturing costs from $1,840,000
to $1,040,000, and have zero disposal value at the end of...

A computer chip manufacturer finds that, historically, for ever
100 chips produced, 85 meet specifications, 10 need reworking, and
5 need to be discarded. Ten chips are chosen for inspection. A)
What is the probability that all 10 meet specs? B) What is the
probability that 2 or more need to be discarded? C) What is the
probability that 8 meet specs,1 needs reworking, and 1 will be
discarded?
