It takes an average of 13.2 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 70 injured patients to immediately tell the truth about the injury and noticed that they averaged 13.4 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.52 minutes. What can be concluded at the the a = 0.10 level of significance? %3D a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Но: ? 0 Select an answer H1: ? O Select an answer C. The test statistic ? 8 is 0.475. Enter it here (please show your answer to 3 decimal places.)
