Question

quality-control inspector of a production plant will reject a batch of syringes if two or more defective syringes are found in a random sample of ten syringes taken from the batch. Suppose the batch contains 5% defective syringes.

(a) What is the expected number of defective syringes the inspector will find? (Enter a number. Enter your answer to two decimal places.)

(b) What is the probability that the batch will be accepted? (Enter a number. Round your answer to three decimal places.)

(c)Find σ (in terms of the number of syringes). (Enter a number. Round your answer to three decimal places.)

Answer #1

The quality-control inspector of a production plant will reject
a batch of syringes if two or more defective syringes are found in
a random sample of ten syringes taken from the batch. Suppose the
batch contains 5% defective syringes. Find μ (in terms of the
number of syringes). (Enter a number. Enter your answer to two
decimal places.) What is the expected number of defective syringes
the inspector will find? (Enter a number. Enter your answer to two
decimal places.)...

The quality-control inspector of a production plant will reject
a batch of syringes if two or more defective syringes are found in
a random sample of twelve syringes taken from the batch. Suppose
the batch contains 1% defective syringes.(a) Make a histogram
showing the probabilities of
r = 0, 1, 2, 3, ,
11 and 12 defective syringes in a random sample of twelve
syringes.
(b) Find μ. (Enter your answer to two decimal
places.)

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.

the quality control inspector of a production plant
will reject a batch of syringes if two or more defective syringes

C: what is the probability that the batch...

A quality control inspector has drawn a sample of 14 light bulbs
from a recent production lot. If the number of defective bulbs is 1
or less, the lot passes inspection. Suppose 20% of the bulbs in the
lot are defective. What is the probability that the lot will pass
inspection? Round your answer to four decimal places.

A quality control inspector has drawn a sample of 19 light bulbs
from a recent production lot. If the number of defective bulbs is 2
or more, the lot fails inspection. Suppose 30% of the bulbs in the
lot are defective. What is the probability that the lot will fail
inspection? Round your answer to four decimal places.

Andrew is a quality control inspector at a clothing factory. At
the end of each day, he checks the number of imperfections found in
cotton sweaters. The table below represents the probability density
function for the random variable X, the number of imperfections
found in cotton sweaters per day. Find the standard deviation of
X.
Round the final answer to two decimal places.
