Question: The research department of an appliance manufacturing firm has developed a solid-state switch for its blender that the department claims will reduce the percentage of appliances being returned under the one-year full warranty by a range of 3% to 6%. To determine if the claim can be supported, the testing department selects a group of the blenders manufactured with the new switch and the old switch and subjects them to a normal year's worth of wear. Out of 250 blenders tested with the new switch, 9 would have been returned. Sixteen would have been returned out of the 250 blenders with the old switch. Use a statistical procedure to verify or refute the department's claim.
