n a science fairproject, 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 lefthand, and then she asked the therapists to identify the selected hand by placing their hand just underEmily's hand without seeing it and without touching it. Among 318 trials, the touch therapists were correct 151 times. Complete parts(a) through(d).

a. Given that Emily used a coin toss to select either her right hand or her lefthand, what proportion of correct responses would be expected if the touch therapists made randomguesses? an integer or a decimal. Do notround.
