A manufacturer of power meters, which are used to regulate energy thresholds of a data-communications system, claims that when its production process is operating correctly, only 10% of the power meters will be defective. A vendor has just received a shipment of 14 power meters from the manufacturer and 5 have some form of defect. The vendor wants to test whether the proportion defective is actually greater than 10%.
