When she was 9 years of age, a girl did a science fair experiment in which she tested professional touch therapists to see if they could see 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 without seeing it and without touching it. Among 240 trials, the touch therapists were correct 104 times. Use a 0.05 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective? A) The test statistic for this hypothesis test is ____. (round to two decimal places) B) The P-value for this hypothesis test is ___. (round to four decimal places as needed)
