It takes an average of 9 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 53 injured patients to immediately tell the truth about the injury and noticed that they averaged 3.4 minutes for their blood to begin clotting after their injury. Their standard deviation was 3.1 minutes. What can be concluded at the the or = 0.05 level of significance? 3- For this studs we shuuld use b. The null and alternative hypotheses would be: Ha: ICI 3.: .:1 c. The test statistic = C] [please show your answer to 3 decimal places.} d. The p-value = C] {Please ShD'W your answer to 4 decimal places.) e. The p-value is or f. Based on this, we should the null hypothesis. g. Thus, the final conclusion is that O The data suggest the populaton mean is signicantly less than 5 at o: = 0.05, so there is statistically significant evidence to conclude that the population mean time for blood to begin clotting after an injury if the patient is told the truth immediately is less than 9. O The data suggest the population mean is not significantly less than 5| at o: = 0.05, so there is statistically significant evidence to conclude that the population mean time for blood to begin clotting after an injury if the patient is told the truth immediately is equal to 9. O The data suggest that the population mean is not signicantly less than 5 at o: = 0.05, so there is statistically insignificant evidence to conclude that the population mean time for blood to begin clotting after an injury if the patient is told the truth immediately is less than 9
