A sample of 900 computer chips revealed that 48 % of the chips fail in the first 1000 hours of their use. The company's promotional literature claimed that 52% fail in the first 1000 hours of their use. Is there sufficient evidence at the 0.02 level to dispute the company's claim? State the null and alternative hypotheses for the above scenario.
