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 309 trials the touch therapists were correct 147 times Complete parts a through d ACCES u Usily cimy sample results what is the best part is on the cas des 0 476 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 0 429 p 0 523 Round to three decimal places as needed d What do the results suggest about the ability of touch therapists to select the correct hand by sensing energy fields OA Since the upper confidence limit is above 0 5 there appears to be evidence that touch therapists can select the correct hand by sensing energy fields OB Since the confidence interval is not entirely below 0 5 there appears to be evidence that touch therapists can select the correct hand by sensing energy fields OC Since the lower confidence limit is below 0 5 there does not appear to be sufficient evidence that touch therapists can select the correct hand by sensing energy fields OD Since the confidence interval is not entirely above 0 5 there does not appear to be sufficient evidence that touch therapists can select the correct hand by sensing energy fields
