A librarian wants to check a sample of books from the library to get an idea of how many need replacing.
Why might simple random sampling be a good way to do this?
He will not need a list of all the books
He will take longer if he checks all the books instead of checking a few
He will have a more representative sample if he chooses randomly
He will be able to choose whichever books he likes because it is random
