Question

A quality control department randomly selects 300
motors from a ship and inspects

them for being good or defective. If this sample contains more than
eight defective

motors, the entire shipment is rejected. Assume that 2% of all
motors received are

defective.

a) Find the probability that the given shipment will be
accepted.

b) Find the probability that the given shipment will be
rejected.

Answer #1

You can get the probability in part (a) using Excel command

=BINOM.DIST(7,300,0.02,TRUE)

Suppose a shipment of 180 electronic components contains 3
defective components. To determine whether the shipment should be
accepted, a quality-control engineer randomly selects 3 of the
components and tests them. If 1 or more of the components is
defective, the shipment is rejected. What is the probability that
the shipment is rejected?

Perez Electronics buys monitors for its computers from another
company. The monitors are received in shipments of 100 boxes, each
containing 20 monitors. The quality assurance department at Perez
Electronics first randomly selects one box from each shipment and
then randomly selects 5 monitors from that box. The shipment is
accepted if not more than 1 of 5 monitors is defective. The quality
control inspector at Perez Electronics selected a box from a
recently received shipment of monitors. Unknown to...

The department of quality control of a factory has
establish a lot that contains 90% or more of good items is a lot of
good quality. It has been establish to the following plan. A sample
is taken of 4 items, if 1 o none is defective then the lot is
accepted. A second sample is taken with 2 items, if the second
sample does not contain defective items then the lot is accepted.
If not, then it will be...

When purchasing bulk orders of batteries, a toy
manufacturer uses this acceptance sampling: randomly selects and
test 38 batteries and determine whether each is within
specification. the entire shipment is accepted if at most 2
batteries do not meet specification. a shipment contains 6000
batteries and 1% of them do not meet specification. what is the
probability that this whole shipment will be accepted?will almost
such Shipman be accepted or will many be rejected?

The quality assurance engineer of televisions inspects TV's from
a large factory. She randomly selects a sample of 18 TV's from the
factory to inspect. Assume that 31% of the TV's in the lot at
silver. Let Y be the number of silver TV's selected.
A) find the probability that at least 6 of the TV's selected are
silver.
B) find the probability that less than 4 of the TV's selected
are silver.
C) find the probability that between 3.5...

In a shipment of 300 processors, there are 12 defective
processors. A quality control consultant randomly collects 6
processors for inspection to determine whether they are defective.
Use the Hypergeometric approximation to calculate the
following:
a) The probability that there are exactly 2 defectives in the
sample
b) The probability that there are at most 5 defectives in the
sample, P(X<=5).

Eagle Fitness, Inc. is
testing the quality of its new electronic fitness band called the
Talon. Eagle has received a shipment of 15 fitness bands that
contains 3 defective fitness bands and 12 non defective fitness
bands. Suppose Eagle's quality control manager selects four fitness
bands at random. from the 15 fitness bands and inspects them. Let
the random variable X denote the number non defective fitness bands
in the random sample.

probability distribution of X (PLEASE SHOW...

Brooklyn Corporation manufactures DVDs. The machine that is used
to make these DVDs is known to produce 6% defective DVDs. The
quality control inspector selects a sample of 100 DVDs every week
and inspects them for being good or defective. If 8% or more of the
DVDs in the sample are defective, the process is stopped and the
machine is readjusted. What is the probability that based on a
sample of 100 DVDs the process will be stopped to readjust...

The quality-control inspector of a production plant will
reject a batch of syringes if two or more are found in a random
sample of 10 syringes taken from the batch. Suppose the batch
contains 5% defective syringes. (a) Find the mean? (b) What is the
expected number of defective syringes the inspector will find? (c)
What is the probability that the batch will be accepted? (d) Find
the standard deviation. Round to three decimal places.
