An automobile manufacturer is considering using robots for part of its assembly process. Converting to robots is an expensive process, so it will be undertaken only if there is strong evidence that the proportion of defective installations is less for the robots than for human assemblers. Let p denote the actual proportion of defective installations for the robots. It is known that the proportion of defective installations for human assemblers is 0.02. (a) Which of the following pairs of hypotheses should the manufacturer testH_0: p=0.02 versus H_a: p<.02orH_0: p=0.02 versus H_a: p>.02Explain your answer. b. In the context of this exercise, describe Type I and Type II errors. c. Would you prefer a test with α= .01 or α= .1? Explain your reasoning.
