Solution 4 of 4 B Tables A sample of 900 computer chips revealed that 66 % of the chips fail in the first 1000 hours of their use. The company's promotional literature states that 68 % 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. Is there enough evidence at the 0.02 level to support the manager's claim? When performing a hypothesis test using P-values: |f the P-value is less than or equal to a, then reject the null hypothesis. If the P-value is greater than a, then we fail to reject the null hypothesis. Comparing the P-value we calculated to the level of significance, we see that 0.1971 > 0.02, so we fail to reject the null hypothesis. Since we failed to reject the null hypothesis, that means that there is not sufficient evidence to support the claim that the percentage of chips that fail is different from 68 % . Correct Answer: There is not sufficient evidence to support the claim that the percentage of chips that fail is different from 68 % .
