A sample of 1400 computer chips revealed that 47% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 50% of the chips do not fail in the first 1000 hours of their use. The quality control manager wants to test the claim that the actual percentage that do not fail is different from the stated percentage. Determine the decision rule for rejecting the null hypothesis, H0, at the 0.02 level.
