Question

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 lippada con to select ether her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing the band just under Emily's hand without seeing it and without touching it anong 314 trials, the touch therapists were correct 16 times. Complete partslal through id) a. Given that Emily used a coin loss to select either her right hand or her left hand, what proportion of correct responses would be expected if the touch therapists made random quotes? Type an integer or a decimal Do not round) b. Using Emily's sample results what is the best point estimate of the therapists success rato? Round to three decimal places as needed c. Using Emilys sample to construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists (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 edi? O Since the upper confidence imit 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 6.5, there appears to be evidence that touch therapists can select the correct hand by sensing energy felds OC Since the confidence interval is not only above there does not appear to be silentovidence that touch therapists can select the comect hand by Sensing energy Gelds OD Since the lower confidence imit is below 05. there does not appear to be sufficient evidence that touch therapists can select the correct hand by sending energy Felds Click to select your answers) ary Statistics, 130 Pearson and mures (COMID-19 tapyright 2020 Pearson Education Inc Arights reserved.
