It takes an average of 9.9 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 65 injured patients to immediately tell the truth about the injury and noticed that they averaged 9 minutes for their blood to begin clotting after their injury. Their standard deviation was 2.39 minutes. What can be concluded at the the a= 0.05 level of significance? a. For this study, we should use Select an answer b.

Transcribed Image Text:It takes an average of 9.9 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
65 injured patients to immediately tell the truth about the injury and noticed that they averaged 9 minutes

The data suggest that the population mean is not significantly less than 9.9 at a = 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 9.9.
O The data suggest the population mean is not significantly less than 9.9 at a = 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 9.9.
O The data suggest the populaton mean is significantly less than 9.9 at a = 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 9.9.
