The p-value is...
less than (or equal to) a
greater than a
This test statistic leads to a decision to...
reject the null
O accept the null
Ofail to reject the null
As such, the final conclusion is that...
There is sufficient evidence to warrant rejection of the claim that the mean difference of post-test
from pre-test is not equal to 0.
O There is not sufficient evidence to warrant rejection of the claim that the mean difference of post-
test from pre-test is not equal to 0.
The sample data support the claim that the mean difference of post-test from pre-test is not equal
to 0.
There is not sufficient sample evidence to support the claim that the mean difference of post-test
from pre-test is not equal to 0.

You wish to test the following claim (Ha) at a significance level of a =
problem, µd
represents a post-test. Each row represents the pre and post test scores for an individual.
0.10. For the context of this
PostTest – PreTest one data set represents a pre-test and the other data set
Ho: ud
Ha: µd + 0
You believe the population of difference scores is normally distributed, but you do not know the standard
deviation. You obtain the following sample of data:
pre-test post-test
