Question
Transcribed Image Text:You wish to test the following claim (HA) at a significance level of a = 0.005. For the context of this
problem, Hd = 42-H1 where the first data set represents a pre-test and the second data set
represents a post-test.
0 - Pri :0H
0<Prf:VH
You belleve the population of difference scores is normally distributed, but you do not know the
standard devlation. You obtain pre-test and post-test samples for n 197 subjects. The average
difference (post - pre) is d = 2.3 with a standard devlation of the differences of sa = 21.4.
What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic=
What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value=
The p-value is.
O less than (or equal to) a
Ogreater than a
This test statistic leads to a decision to.
Oreject the null
O accept the null
O fall 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 o.
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.
