It takes an average of 13.6 minutes for blood to begin clotting after an injury. An EMT wants to see if the average will change if the patient is immediately told the truth about the injury. The EMT randomly selected 43 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 3.16 minutes. What can be concluded at the the a = 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Ho: ? v Select an answer H1: ? v Select an answer c. 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 a f. Based on this, we should Select an answer g. Thus, the final conclusion is that ... the null hypothesis. O The data suggest the population mean is not significantly different from 13.6 at a = 0.01, 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 13.6. O The data suggest that the population mean is not significantly different from 13.6 at a = 0.01, 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 different from 13.6. O The data suggest the populaton mean is significantly different from 13.6 at a = 0.01, 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 different from 13.6.

Question
Transcribed Image Text:It takes an average of 13.6 minutes for blood to begin clotting after an injury. An EMT wants to see if the
average will change if the patient is immediately told the truth about the injury. The EMT randomly
selected 43 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 3.16 minutes.
What can be concluded at the the a = 0.01 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho: ? v Select an answer v
Hj: ? v Select an answer v
c. The test
ic ? 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 ? va
f. Based on this, we should Select an answer v the null hypothesis.
g. Thus, the final conclusion is that ...
O The data suggest the population mean is not significantly different from 13.6 at a = 0.01, 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 13.6.
O The data suggest that the population mean is not significantly different from 13.6 at a = 0.01,
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 different
from 13.6.
O The data suggest the populaton mean is significantly different from 13.6 at a = 0.01, 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 different from 13.6.
