- It takes an average of 11.6 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will change if the patient is immediately told the truth about the injury. The EMT randomly selected 40 injured patients to immediately tell the truth about the injury and noticed that they averaged 12.1 minutes for their blood to begin clotting after their injury. Their standard deviation was 1.76 minutes. What can be concluded at the the a = 0.05 level of significance?
