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 cointo 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 withoutseeing it and without touching it. Among 312 trials, the touch therapists were correct 151 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 therapistsmade 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. Using Emily's sample results, construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists.

a) Expected =312*0.5=156 Answer: 156 b) Point estimate p^=151312=0.484 Answer: 0.484

2. 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 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 300 trials, the touch therapists were correct 135 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? b. Using Emily's sample results, what is the best point estimate of the therapist's success rate? c. Using Emily's sample results, construct a 99% confidence interval estimate of the proportion of correct responses made by touch therapists. d. What do this result suggest about the ability of touch therapists to select the correct hand by seeing…

Do people get stressed out when other people watch them work? To find out, Sean and Shelby recruited 30 volunteers to take part in an experiment. Fifteen of the subjects were randomly assigned to complete a word search puzzle while Sean and Shelby stood close by and visibly took notes. The remaining 15 were assigned to complete a word search puzzle while Sean and Shelby stood at a distance. After each subject completed the word search, they completed a second word search under the opposite treatment. The amount of time required to complete each puzzle was recorded for each subject. Explain why these are paired data. These are paired data because they result from Seanand Shelby recorded with Sean and Shelby standing close by and, during a separate time, while Sean and Shelby
