2. When she was 9 years old, 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, then she asked the therapists to identify the selected hand by placing their hand just under Emily's hand without seeing it and touching it. Among the 280 trials, therapists were correct 123 times. Do the data provide sufficient evidence to indicate that touch therapists are effective? Test at the 1% level with both the critical value and p-value methods.
