Question
A group of physicians were subjected to a polygraph (or lie detector). In the experiment half of the participants were instructed to tell the truth and the other half were instructed to lie. The polygraph is not perfect and would indicate that some of the truth-tellers were liars and that some of the liars were truth-tellers. In the application of a polygraph test, an individual is presumed to be a truth-teller (Null hypothesis, Ho) until “proven“ a liar (Alternative hypothesis, H.). In this context of polygraph testing: (a) What is a Type I error? Explain in no more than one sentence. (b) What is a Type II error? Explain in no more than one sentence.
