Production records indicate that 2.1% of the light bulbs produced in a facility are defective. A random sample of 35 light bulbs was selected.
a. Use the binomial distribution to determine the probability that fewer than three defective bulbs are found.
b. Use the Poisson approximation to the binomial distribution to determine the probability that fewer than three defective bulbs are found.
c. How do these two probabilities compare?

It is estimated that
2.1%
of the quartz heaters produced in a certain plant are defective.
Suppose the plant produced 12,000
such heaters last month. Find the probabilities that among
these heaters, the following numbers were defective.

The probability that fewer than 239 parts are defective is
(Round to four decimal places as needed.)
(b) More than 263
The probability more than 263 are defective is
(Round to four decimal places as needed.)

for defects, a random sample of 100 tablets is drawn (without
replacement) and tested. Let X be the random variable that counts
the number of defective units among the sample.

A simple random sample of 105 analog circuits is obtained at
random from an ongoing production process in which 30% of all
circuits produced are defective.
Let ?X be a binomial random variable corresponding to the number
of defective circuits in the sample. Use the normal approximation
to the binomial distribution to compute ?(26≤?≤36) , the
probability that between 26 and 36 circuits in the sample are
defective.
Report your answer to two decimal places of precision.
