It takes an average of 14.9 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 52 injured patients to immediately tell the truth about the injury and noticed that they averaged 15.2 minutes for their blood to begin clotting after their injury. Their standard deviation was 2.49 minutes. What can be concluded at the the α = 0.10 level of significance? For this study, we should use Select an answer t-test for a population mean z-test for a population proportion The null and alternative hypotheses would be: H0: ? p μ Select an answer > < = ≠ H1: ? p μ Select an answer < ≠ = > The test statistic ? z t = (please show your answer to 3 decimal places.) The p-value = (Please show your answer to 4 decimal places.) The p-value is ? ≤ > α Based on this, we should Select an answer reject accept fail to reject the null hypothesis. Thus, the final conclusion is that ...
