### Experiment on Professional Touch Therapists' Ability to Sense Energy FieldsIn 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 310 trials, the touch therapists were correct 149 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 Emily’s sample results, what is the best point estimate of the therapists’ success rate?**- *(Round to three decimal places as needed.)*---**c.

What do the results suggest about the ability of touch therapists to select the correct hand by sensing energy fields?**- 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 fields.- B. 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.- C. 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.- D. 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.---**Click to select your answer(s):**---The image contains options for multiple-choice answers and sections to input numerical responses related to statistical analysis within an educational framework.

Name: ID: A 8. An experiment is conducted to sce if learning while using an online website is as effective as leaming from a teacher who is lecturing. Fifty college students volunteer and will be randomly placed into two groups. One group of voluntcers will be given a lesson online and the qther group will have a teacher explain the lesson. After the lcsson, a test will be given to sec which group, on average, scores higher. What is the purpose of random assignment in the context of this experiment? So that both groups will have exactly twenty-five voluntcers. b. a. So that both groups of voluntcers are roughly cquivalcnt at the beginning of the experiment. So that if there are many voluntcers that prefer leaming online, thcy will be all be placed into the same group. d So that if two of the voluntcers know each other, they will be split into different c. groups. ffect the choire of snack a person cats.

A 9-year-old girl did a science fair 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 her hand without seeing it and without touching it. Among 257 trials, the touch therapists were correct 105 times. Use a 0.01 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective?
