For example, suppose that you are evaluating a home care program for the elderly and you want to talk to the program's clientele you plan to draw a sample of 30% of them, but you can expect that about 20% of the clients will be ineligible for an interview (due to dementia, for example) so you remove them from the sample. What is the probability that any given client will end up in the final sample? A 16 B 24 C 30 ProBock 4440 0 7

Explanation / Answer

Probability that any given client will end up in final sample:

=Probability that the client will be in first sample x Probability that the client is eligible

=Probability that the client will be in first sample x (1 - Probability that the client is ineligible)
