Inga, 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?

Kai did bc it is from the libraries entire catalog so it could be any genre so it would produce an unbiased sample :)
