It takes an average of 10.9 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will increase if the patient is immediately told the truth about the injury. The EMT randomly selected 63 injured patients to immediately tell the truth about the injury and noticed that they averaged 11.3 minutes for their blood to begin clotting after their injury. Their standard deviation was 1.39 minutes. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use t-test for a population mean b. The null and alternative hypotheses would be: Ho: " H₁: PV> 10.9 10.9 c. The test statistic tv = 2.284 d. The p-value = e. The p-value is ? ✓ a f. Based on this, we should Select an answer the null hypothesis. (please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.)
