In a science fair project: Emily conducted an experiment in which she tested professional touch therapists to see ifthey 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 335 trials the touch therapists were correct 155 times. Complete parts (a) through (d). a. Given that Emily used a coin toss to select either her right hand or her left hand. what proportion of correct responses would be expected if the touch therapists made random guesses? (Type an integer or a decimal Do not round) b. Using Emi y's sample results, what is the best point estimate ofthe therapists' success rate? (Type an integer or a decimal. Do not round.) c. Using Emi y's sample results. constructa 95% confidence interval estimate ofthe proportion of correct responses made by touch therapists.
