A sample of 1500 computer chips revealed that 37% of the chips fail in the first 1000 hours of their use. The company's promotional literature states that 39% of the chips fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that fail is different from the stated percentage. Find the value of the test statistic.
