12. (a) Name a situation when we would need the (a) hypergeometric distribution;
We need to use the hypergeometric distribution when we have to determine the
number of successes in a sequence of n draws from a finite population without
replacement.
Here is an example:
“ABC Computers manufactures personal computers at 2 plants. The Texas plant
has 40 employees, the Hawaii plant has 20. A random sample of 10 employees
is to be asked to fill out benefit questionnaires.
What is the probability that none of the employees in the sample work at the
Hawaii plant
(b) geometric distribution;
The geometric distribution can be used to model the number of births up to (and
including) a boy's birth
(c) uniform distribution.
We can use a uniform random number generator to determine the winner of a raffle.
