Discussion Question

In each of the following cases, decide whether a binomial distribution is an appropriate model, and give your reasons.

 1.  A firm uses a computer-based training module to prepare 20 machinists to use new numerically controlled lathes.  The module contains a test at the end of the course; X is the number who perform satisfactorily on the test.

 2.  The list of potential product testers for a new product contains 100 persons chosen at random from the adult residents of a large city.  Each person on the list is asked whether he or she would participate in the study if given the chance; X is the number who say "Yes".

 3.  Either in a job you currently have or one that you would like to have, describe a data set you could collect that would be in the binomial setting.
