Catherine finds that in a randomly selected sample of 500 families in her home town, 45% own at least one computer. Her research shows that there are a total of 35,000 families in her town. Which statements are true? Select each correct answer. A To estimate the percentage well, she would need to collect data for all 35,000 families. B If she collected data for a random sample of 1000 families in her home town, then that percentage would be a better estimate for the percentage of all 35,000 families that own a computer. C Since her sample was only 500 families, it is not possible that the percentage is a good estimate for the percentage of all 35,000 families that own a computer. D Since her sample was randomly selected, she can reasonably infer that about 45% of the 35,000 families in her town own at least one computer.
