When she was 14 years of age, Emily Rosa did a science fair 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 244 trials, the touch therapists were correct 113 times. Use a 0.08 significance level to test the claim that touch therapists use a method that is different from random guesses. Do the results suggest that touch therapists are effective?
