Question

As a quality-control inspector for toy trucks, you have observed that 4% of the time, the wooden wheels are bored off-center. If 6 wooden wheels are used on each toy truck produced, what is the probability that a randomly selected toy truck has no off-center wheels? (Give your answer correct to three decimal places.)

Answer #1

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 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. (Select the correct
graph.)
c-What is the probability that the batch will be accepted?...

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.

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 six syringes taken from the batch. Suppose the
batch contains 5% defective syringes.

Buffalo Company manufactures toy trucks. Orders for 7,300 trucks
were received during March, with deliveries scheduled evenly
throughout the month of April. Trucks are produced simultaneously
in 10 manufacturing cells. Time available for production in each
cell is 7 hours per day for 21 days during March.
Calculate the takt time. (Round answer to 1 decimal
place, e.g. 15.2.)

You
are a quality control manager in a chainsaw manufacturer company,
producing chainsaws in 4 different sizes in three factories. Each
day, Factory 1 produces 21 small and 21 medium chainsaws; Factory 2
produces 21 medium and 21 large chainsaws; and Factory 3 produces
14 medium, 14 large and 14 extra large chainsaws. Assuming that you
select 6 products randomly for quality control purposes, what is
the probability that you will find 6 large chainsaws, at least 5 of
which...
