Question 14, 7.1.21-T HW Score: 73.63%, 25.03 of 34 points Save Part 4 of 4 Points: 0.8 of 1 in a scioco fair project Emily conducted an experiment in which she tested professional touch thorapists to see if they could sense hof energy field She flipped a con to select other her night 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 144 times. Complete parts () through (d) a. Given that Emily used a coin toss to select other her right hand of her left hand what proportion of correct responses would be expected if the touch therapists made random guesses? 50 (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 rate? 466. (Round to three decimal places as needed) c. Using Emily's sample results, construct a 95% confidence interval estimate of the proportion of correct responses made by touch therapists 410 <p 522 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 ? O A 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 folds B. Since the upper confidence limit is above 05, there appears to be evidence that touch therapists can select the correct hand by sensing energy fields OC. Since the confidence interval is not entirely above 05, there does not appear to be sufficient evidence that touch therapists can select the correct hand by sensing onergy fields OD. Since the lower confidence it is below 0.5, there does not appear to be sufficient evidence that touch therapists can select the correct hand by sensing energy fields a
