In the past few years, outsourcing overseas has become more
frequently used than ever before by U.S. companies. However,
outsourcing is not without problems. A recent survey by
Purchasing indicates that 20% of the companies that
outsource overseas use a consultant. Suppose 15 companies that
outsource overseas are randomly selected.
a. What is the probability that exactly four
companies that outsource overseas use a consultant?
b. What is the probability that more than nine
companies that outsource overseas use a consultant?
c. What is the probability that none of the
companies that outsource overseas use a consultant?
d. What is the probability that between five and
seven (inclusive) companies that outsource overseas use a
consultant?

More than 100 million people around the world are not getting
enough sleep; the average adult needs between 7.5 and 8 hours of
sleep per night. College students are particularly at risk of not
getting enough shut-eye. A recent survey of several thousand
college students indicated that the total hours of sleep time per
night, denoted by the random variable X, can be approximated by a
normal model with E(X) = 6.94 hours and SD(X) = 1.23 hours.
