A sample of 1300 computer chips revealed that 43% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature claimed that more than 40% do not fail in the first 1000 hours of their use. Is there sufficient evidence at the 0.10 level to support the company's claim? State the null and alternative hypotheses for the above scenario.
