The failure rate model above is used to show a typical relationship of many parts between their failure rate and the time in service. The reliability function for period "B" is BEST represented by

Measurement gaging is preferable to go, no-go gaging of a quality characteristic because

Given that the population standard deviation is 6.8, what sample size is required to be 90% confident that the estimated mean has an error less than 0.02?

In the failure rate model shown below, which one of the sections represents the period when catastrophic failures are likely to occur?

The maximum allowable percent defective for the process average is the
