Answer to Question 1

The claim is that the defect rate has decreased and is now less than 9. If the overall defect rate were still 9, it would be extremely unlikely that a shipment of 250 washing machines would contain as few as 2 defectives. Therefore the claim that the defect rate has decreased is probably correct.

Answer to Question 2
