A new quality-inspection program is being tested to see if it will reduce the proportion of parts shipped out that are defective. Under the old program, the proportion of defective parts was 0.10. Two hundred parts that passed inspection under the new program will be sampled, and the number of defectives will be counted. The new program will be implemented if it is shown that the proportion of defectives is less than 0.10.
