Suppose that, next month, the quality control division will
inspect 80 units. Among these, 56 will undergo a speed test and 24
will be tested for current flow. If an engineer is randomly
assigned 3 units, what are the probabilities that:
a) none of them will need a speed test?
b) only 2 will need a speed test?
c) at least 2 will need a speed test? Evaluate these solutions using the hypergeometric distribution and compare the result using the binomial distribution as an approximation.

Imagine you're buying a $270 million car. You'd want to kick
the tires pretty hard. That's what airlines do with new airplanes.
Delivering one widebody airplane is a big
deallong dash—each
plane has a list price roughly the cost of a high-rise
hotel.

Boeing factories to watch their flying machines...

You work for a soft-drink company in the quality control
division. You are interested in the standard deviation of one of
your production lines as a measure of consistency. The product is
intended to have a mean of 12 ounces, and your team would like the
standard deviation to be as low as possible. You gather a random
sample of 16 containers. Estimate the population standard deviation
at a 80% level of confidence.

Javier Company has sales of $9,800,000 and quality costs of
$1,611,000. The company is embarking on a major quality improvement
program. During the next three years, Javier intends to attack
failure costs by increasing its appraisal and prevention costs. The
"right" prevention activities will be selected, and appraisal costs
will be reduced according to the results achieved. For the coming
