Say that a simple random sample of size 15 will be drawn from a population comprised of N members, exactly 30% of whom own a car. Provide answers to the following to three decimal places. (a) Computing directly using the definition of a probability sample, and presuming that the population size is N = 160, what is the chance that at most one of those sampled owns a car? (b) And if instead the population size is N =2*160, what is the chance that at most one of those sampled owns a car?

![Say that a simple random sample of size 15 will be drawn from a population comprised of N members,
exactly 30% of whom own a car. Provide answers to the following to three decimal places.
(a) Computing directly using the definition of a probability sample, and presuming that the population size
is N = 160, what is the chance that at most one of those sampled owns a car?
(b) And if instead the population size is N =2*160, what is the chance that at most one of those sampled
owns a car?
NOTE: It is worth comparing your answers to (a) and (b). Is the size of the population playing an important
role in the chance of getting a very non-representative sample?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc6c24633-c3cc-42f6-867b-8e6b80becf9d%2Ffc6c5c15-dad2-42da-a104-9fdac69b7c08%2Fsyfph0a_processed.png&w=3840&q=75)
