It takes an average of 12.1 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will decline if the patient is immediately told the truth about the injury. The EMT randomly selected 49 injured patients to immediately tell the truth about the injury and noticed that they averaged 10.6 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.31 minutes. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: H₁: Select an answer Select an answer c. The test statistic | (please show your answer to 3 decimal places.)

![**Do Blood Clotting Times Decrease with Honesty?**
It takes an average of 12.1 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will decline if the patient is immediately told the truth about the injury. The EMT randomly selected 49 injured patients to immediately tell the truth about their injury and noticed that they averaged 10.6 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.31 minutes. What can be concluded at the the α = 0.01 level of significance?
**Analysis Steps:**
a. **Choosing the Appropriate Test:**
- For this study, a statistical test needs to be selected from the choices.
b. **Hypotheses Formulation:**
- Null Hypothesis (\(H_0\)): [Select an option] — typically indicates no change or effect.
- Alternative Hypothesis (\(H_1\)): [Select an option] — suggests a decrease in the average clotting time.
c. **Calculating the Test Statistic:**
- Compute the test statistic value: [Enter answer] (please show your answer to three decimal places).
This setup helps students understand hypothesis testing in medical or emergency response scenarios, fostering critical thinking on whether timely honesty impacts physiological responses like clotting time.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F5480d4d1-ea31-4a53-998f-6e5504770643%2Fb7ebec09-339f-4162-9bff-500910f406c7%2Fnva143_processed.jpeg&w=3840&q=75)
