What is the emitter voltage? The collector voltage?

What is the emitter voltage? The collector voltage?

A semiconductor manufacturer collects data from a new tool and conducts a hypothesis test with the null hypothesis that a critical dimension mean width equals 100 nm. The conclusion is to not reject the null hypothesis. Does this result provide strong evidence that the critical dimension mean equals 100 nm? Explain.

The life span of a calculator battery is normally distributed with a mean of 45 hours and a standard deviation of 5 hours. What is the probability that a battery lasts more than 53 hours?

The standard deviation of critical dimension thickness in semiconductor manufacturing is σ = 20 nm. a. State the null and alternative hypotheses used to demonstrate that the standard deviation is reduced. b. Assume that the previous test does not reject the null hypothesis. Does this result provide strong evidence that the standard deviation has not been reduced? Explain.
