After a massive inventory, Central Library finds 12% of its volumes missing. As a result, Central institutes new procedures to prevent theft. After instituting these procedures for 1 year, Central Library wants to know whether they are working, but it cannot afford the cost of a complete inventory. The library takes a sample of 200 books and cannot locate 14 of them. These 14 are assumed to be lost to theft. What can you say about the new procedures?
