I NEED HELP ASAP 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.


To estimate the percentage well, she would need to collect data for all 35,000 families.

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.

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.

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.
