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