Filtering the groups

The Metropolitan Public Library's new rating statistics feature is a hit! However, patrons have complained that books with only one or two reviews can have misleading averages. A book with a single 5-star review appears just as highly rated as a beloved classic with hundreds of positive reviews.

The library director has asked you to enhance the system by allowing users to filter out books with insufficient reviews.
