![### Science Fair Experiment Analysis
A 9-year-old girl conducted a science fair experiment to test whether professional touch therapists can sense her energy field. She randomly selected either her right or left hand by flipping a coin and asked the therapists to identify the chosen hand by placing their hand just under her hand without seeing or touching it. Out of 293 trials, the therapists were correct 115 times. We are using a 0.01 significance level to test if touch therapists employ a method better than random guessing.
#### Hypotheses
Identify the null and alternative hypotheses for this test. Choose the correct answer below:
- **A.** \(H_0: p = 0.5\)
\(H_1: p < 0.5\)
- **B.** \(H_0: p \neq 0.5\)
\(H_1: p = 0.5\)
- **C.** \(H_0: p = 0.5\)
\(H_1: p \neq 0.5\)
- **D.** \(H_0: p = 0.5\)
\(H_1: p > 0.5\)
#### Test Statistic
Calculate the test statistic for this hypothesis test and round to two decimal places as needed.
- **Test Statistic:** [ ]
#### P-Value
Determine the P-value for this hypothesis test and round to three decimal places as needed.
- **P-value:** [ ]
#### Conclusion
Identify the conclusion for this hypothesis test:
- **A.** Reject \(H_0\). 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 \(H_0\). There is sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses.
- **C.** Reject \(H_0\). There is sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses.
- **D.** Fail to reject \(H_0\). There is not sufficient evidence to warrant rejection of the claim that touch therapists use a method equivalent to random guesses.
#### Effectiveness Conclusion
Do the results suggest that touch therapists are effective?
- The results suggest that the touch therapists performed [ ] random guesses, so they [ ] to be effective](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F747d1b20-8ca2-4147-9934-fb082f00c390%2F3dba503f-f916-48ee-9dbc-a1331604b9b6%2Fe6l5kxa_processed.jpeg&w=3840&q=75)
