Question

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 machine? Round your answer to four decimal places.

Lazurus Steel Corporation produces iron rods that are supposed
to be 36 inches long. The machine that makes these rods does not
produce each rod exactly 36 inches long. The lengths of the rods
are normally distributed and vary slightly. It is known that when
the machine is working properly, the mean length of the rods is 36
inches. The standard deviation of the lengths of all rods produced
on this machine is always equal to 0.035 inch. The quality...

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.

When working properly a machine that used to make
chips for calculation does not produce more than 4% defective
chips,wheanever the machine produces more than 4% defective chips
,it's needs a adjustment. To check if machine is working properly
the quality control department at the company often takes samples
of chips and inspect them to determine if they are good or
defective. One such random sample of 200 chips taken recently from
the productive line contained 12defective chips.use

A machine at Katz Steel Corporation makes 5-inch-long nails. The
probability distribution of the lengths of these nails is
approximately normal with a mean of 5 inches and a standard
deviation of 0.12 inch. The quality control inspector takes a
sample of 25 nails once a week and calculates the mean length of
these nails. If the mean of this sample is either less than 4.95
inches or greater than 5.05 inches, the inspector concludes that
the machine needs an...

A machine at Katz Steel Corporation makes 5-inch-long nails. The
probability distribution of the lengths of these nails is
approximately normal with a mean of 5 inches and a standard
deviation of 0.10 inch. The quality control inspector takes a
sample of 16 nails once a week and calculates the mean length of
these nails. If the mean of this sample is either less than 4.94
inches or greater than 5.06 inches, the inspector concludes that
