In a science fair project, 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 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 286 trials, the touch therapists were correct 137 times. Complete parts (a) through (d). v.5 ( lype an integer or a gecimal. uo not round.) b. Using Emily's sample results, what is the best point estimate of the therapists' success rate? 0.479 (Round to three decimal places as needed.) c. Using Emily's sample results, construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists.
