The Elisa test for the human immunodeficiency virus (HIV) that causes AIDS has been used in the screening of blood donations. As with most medical diagnostics test, the ELISA test is not infallible. If a person actually carries HIV, experts estimate that this test gives a positive result 97.7% of the time (the number is called the sensitivity of the test. If a person does not carry HIV ELISA gives a negative result 92.6% of the time. Suppose that 0.5% of the public carries HIV.

In a science fair project, Emily conducted an experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and without touching it. Among 337 trials, the touch therapists were correct 163 times. Using Emily's sample results, construct a 95% confidence interval estimate of the proportion of correct responses made by touch therapists. (round to 3 decimal places)
