**Question 1:** In a study, a sample of 12 participants rated their pain level as significantly lower when they repeated a swear word than when they repeated a neutral word. Following are the values of swear and neutral words. Calculate a 95% confidence interval at an alpha level of 0.5.| Participant | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 ||-------------|---|---|---|---|---|---|---|---|---|----|----|----|| Neutral word| 5 | 9 | 6 | 1 | 4 | 7 | 7 | 3 | 8 | 9 | 2 | 2 |*Note: The table presents the pain ratings for each participant when repeating a neutral word.*

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 337 trials, the touch therapists were correct 163 times. Using Emily's sample results, construct a 95% confidence interval estimate of the proportion of correct responses made by touch therapists. (round to 3 decimal places)
