Answer #1

The number of weaving errors in a twenty-foot by ten-foot roll
of carpet has a mean of 0.8. What is the probability of observing
less than 2 errors in the carpet? Round your answer to four decimal
places.

The number of weaving errors in a twenty-foot by ten-foot roll
of carpet has a mean of 0.5. What is the probability of observing
exactly 2 errors in the carpet? round your answer to four decimal
places.

The number of weaving errors in a twenty-foot by
ten-foot roll of carpet has a mean of 0.8. What is the probability
of observing more than 4 errors in the carpet?

The mean number of errors per page made by a member of the word
processing pool for a large company is thought to be 2.4 with the
number of errors distributed according to a Poisson distribution.
If a page is examined, what is the probability that more than two
errors will be observed?
The probability that more than two errors will be observed is
.
(Round to four decimal places as needed.)

The number of surface flaws in a plastic roll used in the
interior of automobiles has a Poisson distribution with a mean of

The number of flaws per square yard in a type of carpet material
varies with mean 1.3 flaws per square yard and standard deviation 1
flaws per square yard. This population distribution cannot be
normal, because a count takes only whole-number values. An
inspector studies 167 square yards of the material, records the
number of flaws found in each square yard, and calculates
x, the mean number of flaws per square yard inspected. Use
the central limit theorem to find...

The number of flaws per square yard in a type of carpet material
varies with mean 1.8 flaws per square yard and standard deviation
0.9 flaws per square yard. This population distribution cannot be
normal, because a count takes only whole-number values. An
