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 311​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?

b. Using​ Emily's sample​ results, what is the best point estimate of the​ therapists' success​ rate?

c. Using​ Emily's sample​ results,construct a 90% confidence interval estimate of the proportion of correct responses made by touch therapists.less thanpless thannothing

d. What do the results suggest about the ability of touch therapists to select the correct hand by sensing energy​ fields?

A.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.

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 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.

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.
