It takes an average of 8 minutes for blood to begin clotting after an injury. An EMT wants to see if theaverage will increase if the patient is immediately told the truth about the injury. The EMT randomlyselected 60 injured patients to immediately tell the truth about the injury and noticed that they averaged8.5 minutes for their blood to begin clotting after their injury. Their standard deviation was 1.3 minutes.What can be concluded at the the a = 0.10 level of significance?a. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Ho: ? v Select an answer vH1:? v Select an answer vc. The test statistic ? v =(please show your answer to 3 decimal places.)d. The p-value(Please show your answer to 4 decimal places.)e. The p-value is ? v af. Based on this, we should Select an answer v the null hypothesis.g. Thus, the final conclusion is that..O The data suggest the populaton mean is significantly greater than 8 at a = 0.10, so there isstatistically significant evidence to conclude that the population mean time for blood to beginclotting after an injury if the patient is told the truth immediately is greater than 8.O The data suggest the population mean is not significantly greater than 8 at a = 0.10, so thereis statistically significant evidence to conclude that the population mean time for blood tobegin clotting after an injury if the patient is told the truth immediately is equal to 8.O The data suggest that the population mean is not significantly greater than 8 at a = 0.10, sothere is statistically insignificant evidence to conclude that the population mean time forblood to begin clotting after an injury if the patient is told the truth immediately is greaterthan 8.

Solution:- from given information claim: if the average of 8 minutes will increase if the patient…
