Question
Transcribed Image Text:It takes an average of 13.2 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 55 injured patients to immediately tell the truth about the injury and noticed that they averaged
13.1 minutes for their blood to begin clotting after their injury. Their standard deviation was 2.52 minutes.
What can be concluded at the the a = 0.10 level of significance?
a. For this study, we should use t-test for a population mean
b. The null and alternative hypotheses would be:
Но: v
13.2
%3D
H1: H v
>
c. The test statistic t 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 s va
f. Based on this, we should reject
g. Thus, the final conclusion is that ...
the null hypothesis.
O The data suggest that the population mean is not significantly less than 13.2 at a = 0.10, 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
13.2.
O The data suggest the population mean is not significantly less than 13.2 at a = 0.10, 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 13.2.
O The data suggest the populaton mean is significantly less than 13.2 at a = 0.10, 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 13.2.
