I've started these problems but I am unsure on how to continue.

A sample of 1600 computer chips revealed that 78% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 77% 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 more than the stated percentage. Is there enough evidence at the 0.02 level to support the manager's claim?

Step 1 of 7:State the null and alternative hypotheses.

Step 2 of 7:Find the value of the test statistic. Round your answer to two decimal places.

Step 4 of 7:Determine theP-value of the test statistic. Round your answer to four decimal places.

Step 5 of 7:Identify the value of the level of significance.

Step 6 of 7:Make the decision to reject or fail to reject the null hypothesis.

Step 7 of 7:State the conclusion of the hypothesis test.
