Do the results suggest that touch therapists are​ effective? The results suggest that the touch therapists performed worse than, similarily to,OR better than random guesses, so they appear OR do not appear to be effective? 
 
 
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 267 trials, the touch therapists were correct 116 times. Use a 0.05 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?
Identify the null and alternative hypotheses for this test. Choose the correct answer below.

H1:p#0.5
H1:p<0.5
С. Но: р3D0.5
O D. Ho: p+0.5
H4:p>0.5
H4:p=0.5
Identify the test statistic for this hypothesis test.
The test statistic for this hypothesis test is
(Round to two decimal places as needed.)
Identify the P-value for this hypothesis test.
The P-value for this hypothesis test is
(Round to three decimal places as needed.)
Identify the conclusion for this hypothesis test.
A. Reject Ho. There is not sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses.
B. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses.
O C. Reject Ho. There is sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses.
