Nga, kai, and jason volunteer in the school library. they want to find the average number of pages of a library book. it would be unreasonable to calculate the number of pages in every book to find the average. they decide they need to find a valid sample.
inga suggests choosing 100 books from the history section to get a sample.
kai suggests randomly selecting 100 books from the library’s entire catalog.
jason suggests using 100 books from the teen fiction section to get a sample.
who suggested the best way to produce a random sample that is not biased?
