Large Sample Size. A researcher for a car dealership wants to estimate the mean age of cars in his county. He goes to the largest shopping mall, he randomly selects 3,000 cars in the parking lot, and he obtains their ages from the registration stickers on the car windows. He then computes the mean age of the sample of 3,000 cars. The sample mean is a good estimate of the population mean, because the large sample size compensates for the fact that he is using a convenience sample.

decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly. Not all of these statements have definitive answers, so your explanation is more important than your chosen answer.
