John Johnson, the local sheriff, suspects that many of his city’s residents are operating motor vehicles without current inspection stickers. To determine whether this is true, John has his boys, John, H. R., and Charles, randomly stop 100 cars. Of these 100 cars, 43 do not have current inspection stickers. John decides to put some fear into drivers and launches a public relations campaign threatening to crack down. A month later, John wants to know whether the program worked. A random sample of 100 cars showed that 21 did not have valid inspection stickers. What can you tell John about the program?
