A polygraph (lie detector) is an instrument used to determine if
an individual is telling the truth. These tests are considered to
be 95% reliable. In other words, if an individual lies, there is a
0.95 probability that the test will detect a lie. Let there also be
a 0.090 probability that the test erroneously detects a lie even
when the individual is actually telling the truth. Consider the
null hypothesis, "the individual is telling the truth," to answer
the following questions.
a. What is the probability of a Type I
error? (Round your answer to 3 decimal
places.)
b. What is the probability of a Type II
error? (Round your answer to 2 decimal
places.)
