An engineer is designing an experiment to test if airplane engines are faulty and unsafe to fly.The engineer expects 0.0001% of engines to be unsafe.The null hypothesis is that the probability of an unsafe engine is less than or equal to 0.0001% and the alternative hypothesis is that the probability the engine is unsafe is greater than 0.0001%.
A)Describe the consequences of a Type I and Type II error.
B)Should the engineer design the test with a higher alpha or a higher beta? Explain.
