Suppose the general manager for a company that produces a complicated electronics component used in the navigation systems in automobiles has stated that 69% of the items made pass through the final inspection without needing any rework. The quality manager wished to verify this statement. To do so, she selected a random sample of n = 180 parts at the final inspection station and found that 105 passed and did not require rework.

a. State the appropriate null and alternative hypotheses for testing the general manager’s claim.
b. Using alpha = 0.05, from the sample data, what conclusion should the quality manager reach about the general manager’s claim? Discuss.
