Question 3

A survey was conducted by visiting a student parking lot to estimate the proportion of
cars that were red. Which of the following is NOT correct?

A. If another sample of cars was chosen, it is likely that a different proportion of cars that are red
would be obtained.

B. The sample would be representative of the population if 100 cars were chosen regardless if
randomization was used or not.

C. Even though a random sample was taken from cars in the parking lot, the sample may not be
representative of the cars driven by students because the decision to park in that particular lot is
self-selected.

D. If the sampled stall was empty, we can simply choose another stall, at random, to take its place
because it is not likely that the stall being vacant is related to a car being red.
